As we continue to see the national average in free-throw shooting hover around 70%, it seems like there should be an ever increasing number of candidates threatening the record each season.<\/p>\n<p>It&#8217;s possible that 2017 could be the\u00a0year that a team breaks the record, but this season will probably illustrate why that mark\u00a0is so tough to reach.\u00a0Since 2002, 13 teams have made it to January 16th shooting at least 80% from the free-throw line and three of those cases are this season.\u00a0Most notably, Notre Dame has made 82.8% of its free-throw attempts so far, which is better than the Crimson&#8217;s season-long 82.2% <a href=\"http:\/\/www.sports-reference.com\/cbb\/schools\/harvard\/1984.html\">back in &#8217;84<\/a>. And over the past 16 seasons, no team has been above the 82% mark on this date, so that would seem to bode well for potential free-throw shooting immortality.<!--more--><\/p>\n<p>But alas, if there&#8217;s one thing to learn from history, it&#8217;s that an extreme performance is the sum of great ability and great fortune. The ten previous teams that cleared the 80% at this point in the season finished the season a collective 78.8% from the line. From this point onward, those teams shot 76.8%. They were all very good shooting teams, but whatever good feelings\u00a0existed over the first half of the season could not be duplicated over the second half.<\/p>\n<p>So while Notre Dame has made nearly 83% of its free throws so far, their true ability is probably not that good. When someone says\u00a0&#8220;Notre Dame shoots 83% as a team&#8221; they really mean &#8220;Notre Dame has shot 83% as a team&#8221;. We don&#8217;t know what Notre Dame is shooting right now, in the moment. Based on history I&#8217;d guess something like 78%, but nobody\u00a0can know for sure.<\/p>\n<p>If one does a regression trying to fit season-ending free-throw percentage to January 16th free-throw percentage, Notre Dame is predicted to finish right at 80%. That would make them the tenth-best team in NCAA history, so as a prediction, it&#8217;s fairly encouraging. Remember, records take talent and luck and we can&#8217;t predict luck, so that prediction is assuming no luck whatsoever.<\/p>\n<p>One thing that I thought would benefit the Fighting Irish in this chase is that they don&#8217;t get fouled very often. We&#8217;re at roughly the halfway point of the season and they&#8217;ve attempted 297 free throws which is slightly off the pace of &#8217;84 Harvard&#8217;s 651 attempts and Harvard played just 26 games that year.<\/p>\n<p>It turns out\u00a0my hunch was wrong. From a predictive standpoint, it&#8217;s beneficial for a team to have attempted <em>more<\/em> free throws to this point. More free-throw attempts give us a more reliable estimate of a team&#8217;s ability. Because Notre Dame has shot so few free throws, we can&#8217;t be as confident in the fact that nearly all of their players have improved their shooting over previous career averages.<\/p>\n<p>In fact, Valparaiso, who has made 80.6% of their shots on 449 attempts, is probably about as good as Notre Dame in real life. The Crusaders are\u00a0actually the favorite to lead the country in FT% from this point forward, but since Notre Dame already has a 2.2% advantage in the bank, the Fighting Irish are still the favorite to win the season-long FT% title.<\/p>\n<p>However,\u00a0in terms of producing an extreme performance, it helps that Notre Dame won&#8217;t be going to the free-throw line all that much. We need a lot of luck for this to happen, so the fewer trials the better. In 2011, both Wisconsin and Harvard improved on an first half performance of 80+%, but not enough to beat the record.<span class=\"footnote_referrer\"><a role=\"button\" tabindex=\"0\" onclick=\"footnote_moveToReference_1409_1('footnote_plugin_reference_1409_1_1');\" onkeypress=\"footnote_moveToReference_1409_1('footnote_plugin_reference_1409_1_1');\" ><sup id=\"footnote_plugin_tooltip_1409_1_1\" class=\"footnote_plugin_tooltip_text\">1<\/sup><\/a><span id=\"footnote_plugin_tooltip_text_1409_1_1\" class=\"footnote_tooltip\"><\/span><\/span><\/p>\n<p>But just three of the ten previous teams to break 80% have improved over the second half, and seven of the previous 47 that were above 78% at this point were able to improve. That helps explain why Notre Dame&#8217;s true chances are\u00a0in the 10-20% range to make history based on this analysis. I hope it happens, but even though we&#8217;re halfway through the season, Notre Dame is not nearly halfway to setting the record.<\/p>\n<div class=\"speaker-mute footnotes_reference_container\"> <div class=\"footnote_container_prepare\"><p><span role=\"button\" tabindex=\"0\" class=\"footnote_reference_container_label pointer\" onclick=\"footnote_expand_collapse_reference_container_1409_1();\">&#x202F;<\/span><span role=\"button\" tabindex=\"0\" class=\"footnote_reference_container_collapse_button\" style=\"display: none;\" onclick=\"footnote_expand_collapse_reference_container_1409_1();\">[<a id=\"footnote_reference_container_collapse_button_1409_1\">+<\/a>]<\/span><\/p><\/div> <div id=\"footnote_references_container_1409_1\" style=\"\"><table class=\"footnotes_table footnote-reference-container\"><caption class=\"accessibility\">References<\/caption> <tbody> \r\n\r\n<tr class=\"footnotes_plugin_reference_row\"> <th scope=\"row\" class=\"footnote_plugin_index_combi pointer\"  onclick=\"footnote_moveToAnchor_1409_1('footnote_plugin_tooltip_1409_1_1');\"><a id=\"footnote_plugin_reference_1409_1_1\" class=\"footnote_backlink\"><span class=\"footnote_index_arrow\">^<\/span>1<\/a><\/th> <td class=\"footnote_plugin_text\">Harvard added another free-throw distinction to its history that season, finishing with the best free-throw percentage to not win\u00a0the season title (80.8%).<\/td><\/tr>\r\n\r\n <\/tbody> <\/table> <\/div><\/div><script type=\"text\/javascript\"> function footnote_expand_reference_container_1409_1() { jQuery('#footnote_references_container_1409_1').show(); jQuery('#footnote_reference_container_collapse_button_1409_1').text('\u2212'); } function footnote_collapse_reference_container_1409_1() { jQuery('#footnote_references_container_1409_1').hide(); jQuery('#footnote_reference_container_collapse_button_1409_1').text('+'); } function footnote_expand_collapse_reference_container_1409_1() { if (jQuery('#footnote_references_container_1409_1').is(':hidden')) { footnote_expand_reference_container_1409_1(); } else { footnote_collapse_reference_container_1409_1(); } } function footnote_moveToReference_1409_1(p_str_TargetID) { footnote_expand_reference_container_1409_1(); var l_obj_Target = jQuery('#' + p_str_TargetID); if (l_obj_Target.length) { jQuery( 'html, body' ).delay( 0 ); jQuery('html, body').animate({ scrollTop: l_obj_Target.offset().top - window.innerHeight * 0.2 }, 380); } } function footnote_moveToAnchor_1409_1(p_str_TargetID) { footnote_expand_reference_container_1409_1(); var l_obj_Target = jQuery('#' + p_str_TargetID); if (l_obj_Target.length) { jQuery( 'html, body' ).delay( 0 ); jQuery('html, body').animate({ scrollTop: l_obj_Target.offset().top - window.innerHeight * 0.2 }, 380); } }<\/script>","protected":false},"excerpt":{"rendered":"<p>The 1984 Harvard Crimson improbably have held the season free-throw percentage record for three decades, even in the face of college basketball players collectively shooting better than ever.
