Apparently, Sherman's numbers really back him up for INTs, which is a surprise to me. Guess I haven't watched enough Seahawks to really take notice.
He was targeted a grand total of 58 times this season (as of January 17 - add two more targets from the 49er's game) and had 8 INT's.
He also gave up 30 receptions, which is over 50% completion rate when targeting him. In addition, addition, give him 7 penalties, which effectively makes this 37 receptions, for a rate of 37/58 (63%).
Boykin allowed 52 receptions and had 3 penalties, for a total of 55/89 (61.7%)
So it's pretty close, but I'd still give Boykin the edge. Sherman is very all or nothing.
And he has an ego to match, which is what I can't stand. I mean, Ochocinco had an ego, but instead of being in your face, everyone liked him and his antics. He was having fun. Sherman just comes across like a douchebag.
