Freeman was a tackling machine himself in 2012, as his 145 tackles rank eighth in NFL history for total stops by a rookie, according to Pro Football Reference.

The all-time record of tackles in a season by a rookie is 174, set by Patrick Willis of the San Francisco 49ers in 2007. Leonard entered Sunday's game needing to average about 13 tackles a game — about three more than his 10 tackles-per-game average — to break Willis' all-time rookie record.

Leonard now has another feather in his cap toward earning the NFL's Defensive Rookie of the Year award. He has stuffed the stat sheets throughout the year, adding seven sacks and four forced fumbles, both of which lead all NFL off-ball linebackers. Leonard also has 11 tackles for loss, three fumble recoveries and one interception.
