Feet, eyes & hips, are the foundation to every good/great corner.
Ball skills & speed are important as well, but technique supersedes all.
Size, arm length & overall physical frame matter too, but not as much as natural foot speed & lateral movement. Idc how ideal sized a CB may be, if he's stiff hipped with bad feet he's not gonna make it at CB.
I think our issue is our Defensive staff places the premium on tackling, they talk about tackling all the time with our DB's, they completely disregard their ability to move or cover, they just want DB's that can hit & the funniest thing about is, we only have about 2 starters in the secondary who are textbook tacklers, the rest are a lot of swing & missers including my boy Amari lol.
Idk what our philosophy is with CB, it seriously seems completely random, but ability to cover down the field & football IQ need to pushed to the forefront, because sooner or later these constant misses & bad evals at CB is going to bite us even more than it already has.
Miami is smack dab in the middle of the region the produces the most CB's in the nation in college & the NFL, yet we can't find 3-4 solid corners to save our lives, it's really Bizarro world.
