The Bears will carry 6 WR's, 3 TE's, 3 QB's, 8 OLinemen, and 5 backfield options, just like last year. That makes for 25 players on offense, leaving space for 25 players on D, and 3 ST'ers.
I am almost positive we will carry 4 RB's and 1 FB. There is absolutely no need for 2 FB's, especially when Forte could step in at FB if injury occurs.
