My thinking is this: We're looking at TB12 being suspended for the first 4 weeks and we only had JG as a backup option. Then we drafted a developmental QB. This is a tough situation to convince a decent veteran to sign up for. At best he's a backup for 4 weeks and then looking at being cut. Who wants to sign up for that? So, I'm not sure that great veteran option is really out there right now. While I don't expect them to make a draft decision on a QB based on being a qualified backup in the first four weeks of his NFL career, I'm just questioning whether this team can succeed with Brissett under center if JG were to go down. If the plan is to bring in a veteran, we'd be looking at 4 QB's on the roster. Considering they've only carried 2 in recent seasons, 4 would certainly be a change in philosophy.
I may be I'm off on my player analysis, but it seemed to me that Cook would be better prepared to step in and take snaps early on instead of Brissett, a guy who appears to need more time to develop. You may certainly be right that none of the round 3 or later prospects would be able to step in if JG got hurt, and there were obviously red flags on Cook that kept a lot of teams away, but to me it was just an interesting choice. Maybe I know nothing about QB's (likely) and Brissett is a better option than Cook early on. I'm firmly in the In BB We Trust camp, so I'm more than happy to be proven wrong.
