Patrick Willis is quite simply the best inside linebacker in the NFL right now, case closed!  The 24-year old Willis is a heat seeking missile for the Niners.  He has played in all 10 games for the 49ers this season and he has 96 tackles, 3 tackles for a loss, 2.5 sacks, 2 forced fumbles, 6 passes defensed and 2 interceptions (1 returned for a TD).  In three years with the Niners, Willis has played in 42 games in which he has made 411 tackles, defensed 21 passes, has 7.5 sacks, forced 5 fumbles and he has 3 interceptions (2 returned for TDs).  Willis just blows up running backs at the point of attack and the 49ers love to have him in the middle of the D.
