The chance of Peyton playing in Houston next season actually is very high. Lets face the truth here, its highly unlikely the Texans will be able to advance in the playoff or even make the playoff this year. But on the other hand, we are not going to finish as one of the top 5-8 worse teams in the NFL. That means, again, we are not going to pick a good QB (or have a higher chance to be a good QB) in the draft, so instead of going for another recycling backup QB or even the likes of RG3 (yikes), the Texans will definitely looking for some washed up old QB to hope they still have something left in the tanks. Peyton, Brees and Rivers (if these 2 somehow will get cut of their teams will go another direction) are the 3 names definitely will be interested by this franchise at this point. If you do not have a young and good QB to build on for the future, this is about the best route you can go for the Texans.
