We should be worried about the speed & quality of both corner spots--always.

Completely agree.

For that reason--& that reason alone--I see this as a potentially HUGE pickup for this coming season.

It's a great pickup, I don't know if I'd say huge.

Robertson DOES have solid coverage skillz--which we probably need more at a Corner spot than at Safety.

Robertson needs to be at safety; he will probably be a pretty good one, and he appears to be a decent tackler... but I have no idea what season you watched last year if you think Robertson (or anybody else) gave us *solid* coverage at corner. The corner spot was a nightmare for us last year, and it's horrifying to think our corner spot is still so weak that we have to consider playing *any* corner that played that position last year.
