I'm all-in on corner in the first. Be it at 15 or trading down. It's just too big of a weakness to count on being fixed in the middle rounds. There's going to be at least 1 or 2 real good receivers to fall to us in the 2nd round that would normally go in the late 1st/early 2nd, there are solid 3-4 defensive lineman available in the middle rounds, there...okay maybe not tight ends, but that's not an immediate need.
I think Fuller is a reach at 15, but if we can trade back a few spots then I'd be fine with him. Ideally it's Denard.
Apropos of nothing, here's the results from the football board mock...which has been going on for a couple months before petering out late in the 5th round (didn't quite get to our 5th round comp. pick) so values have changed, as have needs. Needless to say my first round pick can be thrown away, rendered obsolete a day or two after being selected.
1.15 "Ha Ha" Clinton-Dix, FS, Alabama
2.46 Allen Robinson, WR, Penn State
3.97 Justin Ellis, NT, Louisiana Tech
4.118 Phillip Gaines, CB, Rice
5.157 Brent Urban, DE, Virginia
