I wouldn't put too much stock in a player's listed height/weight....who know from when that's from.
All true. Just pointing out it could be a concern for durability but sometimes " little " guys excel. That said it was brought up somewhat when Grant was forced in starting a bit as a receiver due to injuries. Smaller target and durability were mentioned.
As a DB covering 6'0" to 6'6" receivers with height and wingspan advantages, that's part of the discussion.
Like you said he could be heavier now but he'll be 28 by TC and if his weight hasn't been added by now, chances are he's just a smaller player. Speed, mobility, football IQ can trump the size thing.
No doubt there will be a dozen or more rookie or veteran DB's added before TC. His stats are impressive and he appears able and willing to make a tackle, although I'm more impressed by his knockdowns.
Tackles can be deceiving. A perfect DB gets challenged less and doesn't need to make as many.
I mentioned some very talented Bomber DB's with the same height that had successful careers. Higher weight is not a guarantee of durability, so we'll see how he does etc.
