Nice thinking. But here are my comments:
Where we are drafting is too high for Rice in round 1. There are too many other WRs who are ahead of him on the draft boards: C. Johnson, D. Jarrett, the Shark, Ted Ginn, Jr. and (possibly) Dwayne Bowe. Rice will be 5th or 6th WR taken, and he might still be there when we draft in the 2nd. I'd be surprised if anyone beyond the top 4 is taken in the first round.
If you want to go OL/WR in the first two rounds, then I'd go with Blalock in the 1st and maybe get Rice in the 2nd. Even if Rice isn't there (though I think he will be) there are other options at WR.
Mason Crosby will be long gone by the 4th round. I think he goes anywhere from late 2nd to mid 3rd.
It's too hard to tell about the other picks at this point in time. We won't know who to look at in the later rounds until at earliest the combine. After that, we'll have an idea of who is going where and be able to look at people for 2nd day picks.
But good job and thanks for the input. I'll keep my eyes on the guys you listed.
