I agree. If Bo comes back to the team (and why wouldn't he if he gets cut from the NFL), he has not spent any time with the team this year, and will be a couple of weeks before he gets a chance to fit in and start.
As posted, Jimenez will come off the IR for Johnson, and one of Ramsay, Morencie, (both scratches last week) or DeWitt (currently on IR) will step in for Hudson. Heyward will take Bradley's spot on the corner, but who takes the extra DB spot is a bit of a question. Shannon James is listed as an LB, but I believe can play as a DB if necessary. Hinds is currently listed on the 9 day IR (to protect him from being scooped off the PR), should be available, and is a rookie Non-Import. Bo has currently not been signed.
Although we should be able to fill in pretty well, this leaves the team a little more vulnerable. Hopefully these injuries will be short ones. Hudson appears to be out for a while, but Bradley may only be out briefly based on Drew's report in the scratching post. I hope we come through the next game with fewer injuries ... the bye week was last week.
