Honestly it's the best thing they (Texans) can do.
Mallett is better or at least in the same level of all these QB's, with veteran NFL experience and learning behind the GOAT. IT'S WORTH THE SHOT. I would think that If I were a GM.
Ok they will have to deal with a new contract next season but it's not like he is going to ask for a big pay day, look Edelman this year, no one is going to throw big money at a player with only 1 year of good playing, it doesn't prove ****. Unless he wins 16 games they will be able to manage a friendly deal like 2 years 10 Mi like McCown, and then evaluate better if he's franchise or not.
Win-Win.
DO IT BILLY FOOTBALL.
