ON the topic of mooving Dunta to Corner... uh, I mean Safety, since he supposedly plays corner right now.
He is too small. I know he plays like one, but that's only at the LOS. You move him 10 yards off, and give that RB a head of steam, you'll just hurt Robinson.
We would be much better using a Nickel package as our base D. Take Cushing off the field, since he might not be really ready anyway, and Keep Dunta near the LOS. As poorly as our LBs have played in the past, we should have been doing something similar all along. But we've never had more than 2 viable starting CBs. With the signing of O'Neal, Jacques, Bennette, and the possibility Dunta may play this year, we should be able to find 2 starters, and a highly capable nickel.
I can't think of anyone to play that highly capable nickel other than Dunta. It plays to his strengths, he'll play in the backfield, get after the QB, and cover a slot receiver/tight end every now & then.
