I've seen no proof that those other teams operated differently than the Texans. Maybe their coaching staffs are just flat better.
Maybe you need to look at the moves the Jags made last season signing Campbell/Bouye in FA.
Pats- Signing Gilmore in FA and trading for Cooks
Philly- Signing Jeffery/Torrey Smith/Trading for Ajayi/Signing our very on Brooks and Wiesnewski (SP?) in FA.
Vikings- Reiff/Remmers in FA along with guys that came in very handy in FA like Keenum (Who is the Texans backup QB) and Murray when Cook went down. Would you say Murray would be the best RB on the Texans roster today.
Tell me again what did the Texans do last offseason in FA? This off season they've made moves but all of their FA moves have been 2nd tier FA's.
The contenders make major FA moves, the Texans ?
