In all likelihood, the best slot WR we can hope for at 51 is Bailey or Wheaton. I personally think Swope in the 4th would be really good, the guy looks like a Wes Welker clone, and every team needs a numbers accumulator.
On the outside, Allen, and Patterson, are gone, and I'll bet at least 3 of the 6 of Hopkins, Woods, Patton, Williams, Dobson, and Hunter are gone, and Rogers' name might enter in there too.
If we end up wanting outside talent, we're really set because there are so many options. If we decide we want a slot guy, it's a bit more delicate since we'll likely have to either take someone slightly before we're comfortable doing so, or have to trade around a bit to get into position.
