Gentlemen let me be clear about Martellus Bennett to try and clear up some misconceptions ON BOTH SIDES of this debate within this thread.
Bennett is in Chicago because HE CHOSE to come to Chicago because Brandon Marshall and him are very close friends and have been for a long time. Bennett wanted to come to Chicago to play with Marshall and he chose to come here at a relatively inexpensive rate.
Bennett is also the most COMPLETE tight end in the NFL, he's both a great blocker and a very good receiver for the position. He's big, strong and very fast for his overall size. Plus unlike a lot of the other athletic TEs across the league he is a willing blocker and a VERY GOOD blocker.
He is also not in the least bit mature...if you want to call it immaturity fine...whatever....he's more of a free spirit open minded, doesn't take himself or life too seriously. He's an upbeat guy and there are few people in the NFL like Bennett. He may absolutely come across as immature to some people, but he's also going to be a really good player for the Bears.
He has been known to have shaky hands at times, sometimes he's inconsistent in the way he catches the football. He dropped like three passes in the opening game and then had probably two drops the rest of the season in 2012.
Bennett is a very good player, a major upgrade over Kellen Davis, and as equally a good receiver as Greg Olsen, but also a better blocker and a lot tougher than Olsen.
Is Bennett going to come in here and be a Top-5 TE in the NFL? Probably not, but he's going to be a good upgrade and he's not going to cost a lot of money in the first year of the contract. Year two is when Bennett's salary really jumps up.
