You already know what I think, based on my mock.
Houston trades down to the Saints, who take Leinart at #1. Houston won't deal with the J-E-T-S, because they are AFC and they don't want Leinart to be in the conference. Besides, in last years draft the Texans dealt with the Saints, so they are already somewhat "trading partners," like Denver and Washington.
Bush the goes to the Jets, and Houston drafts Ferguson like they always wanted anyways. In return, Houston will get N.O.'s 1st rounder next year, and either their 2nd or 3rd rounder this year.
Houston gets who they wanted, get two high 1st rounders next year, and 2 high 2nd rounders this year...
Imagine what their draft could look like:
1) OT Ferguson
2a) OG Jean-Gilles
2b) C Greg Eslinger
Can you say....revamped line? Heh.
All for giving up basically nothing...and two top 10 picks probably still coming in 2007...
