We need WR + LB + OL but I think our biggest need at #9 overall is WR.
WR
It has become obvious that Stevie Johnson is a good WR and a nice guy, but not a #1 WR.
More often than not, when it was clutch time... Stevie would get a dumb penalty, drop passes or turn the ball over.
Sorry to say... it was rare that he came up big, and not often enough to compensate for the more frequent mistakes.
LB
We also need another stud linebacker to help stop the run... we found our Kuechly in round 2 last year. If there is another one this year, we'd grab him early, but I think a big WR is a more glaring need. Maybe we can strike gold again in round 2/3. Also, our problem on defense was that our offense wasn't scoring enough points. I also think our D surprised some people this year, which may mean we can get some good vet FA's to address some needs.
OL
It seems like Whaley likes to find other teams castoffs for OL... that's why unless a stud falls, I think we'll more likely plug holes at OL and go for playmakers in the draft early.
