I'll go with "squeezed into the same scheme" in a heartbeat.
A lot have high praise for Minkah but when it comes to technique you'll have some complaining about him as well. He's one (and these aren't my words here, but an assistant coaches) that "like to play the eyes of the QB and ignore the route." He's got his technique issues as well.
Typically, a guy like Brown is "hidden" as a safety due to his lack of technique. You'll see corners slide inside as well in the same circumstances. That's where we find both Fitz and Brown this summer--both with issues in their game, it's just a matter of who makes the fewest mistakes.
That said, Tony does "fit the mold" of your typical corner in the league--tall, big, fast, with a long reach. But, so did John Fulton and he found himself backing up Belue who didn't "fit the mold." A lot want that "mold" for the left corner; some think it's a necessity.
I can only say let it shake out...and while we're at it, let's not discount what move Levi Wallace may make at corner or forget Shy has been getting more and more reps at Star.
