Since tackles are not an official stat, the coaches review all the film (numerous times no doubt) and decide how many tackles (solo/assist) each player had. According to this method, Patrick Willis does hold the unofficial record for tackles in a single season with 226 accredited. At 6'1", nearly 250lbs and running a 4.4s 40, it doesn't seem far fetched :)
This record was broken for Division III by Kyle McGivney from Luther College(IA) on Nov. 6th, 2010 with a total of 183 tackles with one game left on Saturday Nov. 13th. http://www.thonline.com/article.cfm?id=301497
I'll throw out an early leader...Dan Morgan had 25 tackles in SB 38.
In the 2008 season, that is tackle Daniel Federkeil.
As of the 2008 season, that would be defensive tackle Steve McMichael with 191 consecutive games played. Steve McMichael - 191 games (1981-1993)
