I am no college football expert and from reading mock draft information there look to be 3 WR that could go in the top 20 and another 2-3 that could go in the first round. The ones slated for late first are all pretty big guys too.
With that I might like look at who is there at 22 and get BPA for WR or OLB/DE --- maybe trade down a few spots if there are 3 WR's on the board and pick up an extra 2 or 3.
TE, RB, CB and OT are other positions of interest so having an extra 2 or 3 would be nice.
