I don't know how migranes may have affected Patterson but he has only missed one game in 6 NFL seasons, 95/96 games. With the departure of Bellamy/White he and Wyms back up the 3 starters. Plus he resolves a problem at kick return where the Bears were dead last in the NFL. I think I read he could add 8 yards of field position per return.
Bears #1 need now is safety but that can be filled in the draft to compete with Devin Bush. I'd also like the Bears to draft a nickel CB for competition for Skrine. Maybe add a half back too. That's about all the Bears have picks for.
I don't know what the cap position is today but I'm sure Pace is not done signing guys...does he have enough to sign a bigger name at safety? Is there anybody left?
