I dont think Evans automatically goes before us.
Also, I think the phins might like Clayton more than Evans. His times didn't pan out but you watch the tape and you think of him as a fast guy...he plays fast, might be the "best run blocking WR in 5 years", he's very big...I think all-around he'll be a good WR. Evans runs the risk of being a one-dimensional type speedster. Plus if it did come down to drafting a 1st round WR, I'm not comfortable with it being a guy that has a history (good OR bad) with Chris Chambers. Chambers is in a contract year, he could construe drafting a 1st round WR as a slap in the face given the David Boston move. If we can't manage to put his mind at ease, then that could place two friends with a history at odds not only over playing time, but more importantly over money...because the faster Evans starts in his eyes the more he gets in that first pay-day in 4 years. So Evans will be looking to break past Boston or Chambers and if Boston reclaims his old form, Chambers is definitely the easier target.
And if Boston does become the target, there could easily develop a rift between Chambers and Evans, and Boston, who being the temperamental "she" that he's always been over his career, could start goin all crazy. Having a stranger step into that delicate situation gives you more of a chance I think to maintain professionalism.
I wouldn't cry if we got Evans I'd probably jump for joy cuz I think he'll be a great WR, but I would cast a wary eye on the whole situation.
