Bryant isnt an 'unknown' he is a former #1 pick who has started his entire career.
Ideally, I'd like to see a corner in the first (ideally after trading down to whereever in the first would get us an additional 2nd, maybe around 20??) and we start camp with Hobbs and Bryant as starters, the rookie has the inside track at nickel, and Sanders, Webster, Richardson, other mid rounds picks, etc are battling for roster spots, potentially being as high as the nickel. Then Bryant holds the spot until the #1 draft choice takes it from him.
I am VERY OK with the following:
Hobbs
Bryant
Rookie #1
2 of Sanders, Webster, Richardson, other draft picks or whoever shows up in camp.
We will be 4 deep with players who have done well in those roles, and some of them will be playing lesser roles than they have in the past. We will have ample competition so if any of the free agents crap out, we are OK, and we will have our future top corner playing exactly as much as he shows he is ready to, without being under pressure to throw him out there because we have no one else.
Add in the 4 quality safeties we have Harrison, Meriwhether, Sanders and Tank, and the secondary is really starting to take shape.
