I'm not sure about the corner selection. There were others on the board that didn't have major injury concerns, but his production on the field appears to be solid against SEC competition.
Likewise about the OT. Production looks good against BIG competition, but analysts seem to think strength and balance could be problematic. We needed a depth piece here, but I'm not sure we picked the right one. Time will tell, hoping for the best.
I like the DL from Alabama as a 5t rotational piece. Didn't test well in comparison to edge rushers, but has the size to eat blocks and keep the linebackers clean. Has shown some nice flashes, needs to be more consistent, maybe a new role will highlight his abilities.
Overall, I don't love day 4, but will defer to the scouting team until we see them on the field. Days 1 and 2 look like homeruns. Solid defensive draft. I think we will see considerable improvement on that side by mid-season, if not sooner.
