If Mike Williams is Minnesota's guy, then moving to #5 would help them get him, certainly.
However it is still my suspicion that Tampa Bay is tossing out these trade rumors as smokescreen, to get Miami to either take Alex Smith, or trade with someone who will, because the chances are that if Miami is NOT picking in the top 4 picks, Ronnie Brown will make it all the way to #5. Ronnie Brown fits perfectly into their RB profile, and they do have some QBs already. Also, Gruden coached Jason Campbell and David Greene in the Senior Bowl, and I really do think he might like one of those guys. And, at #37, they will certainly get a crack at Campbell...and with their 3rd round pick, they will certainly get a crack at Greene. I also suspect, however, that Tampa may like Mike Williams, as a local kid, and as a BIG receiver (Gruden likes his WRs especially big and tall, in his own words "it makes a difference"). And another thing I noticed is that Gruden went more out of his way to hype Rodgers than Smith, and I am thinking he did that because he senses that San Fran really might take Smith...and Rodgers, as the #1 guy on a lot of teams' draft boards, would draw the most trade-up interest if he fell to #2 and beyond.
And something is going on in Minnesota. I haven't figured it out yet, but the last thing I would call them is "honest" when it comes to the draft, the way things have happened for them in the past. It would certainly make sense for them to try and trade up to get Braylon Edwards, hype him as the next Randy Moss, give Culpepper a nice WR target for years to come. Nobody in Minnesota is going to put their butt in a seat because the Vikings are hyping Troy Williamson. But, they might if they can get Braylon Edwards. They've been very very active in FA on defense. On offense, they may want a guy who can contribute right away, and I'm sure they're wondering to themselves, could Williamson go right away, or could Edwards?
For now, tentatively, I would call a Minnesota trade to #2 VERY possible. I may downgrade, once I've had time to figure out who Minnesota's real target may be at #7.
My estimation for what we would end up with in the case of a trade down, would be the #7, #18, #46, and our 3rd round pick. At those picks, I would probably take Alex Barron at #7 and Matt Jones at #18. After that it gets hard to predict, but I would take either Fason or a DT at #46, and then at 3rd round a RB (if we didn't get Fason), DT (if we didn't get one at #46), or CB. In the 4th round I would be inclined to take a chance on David Greene if he were there (props to KB21, Greene is more his boy than mine).
