at the end of the season as a free agent will be Cassel and Brady returned for the next season, which would Cassel to pay 9.6 million dollars for him to stay in the team or let go and take back to Brady?

I don't think thats even a question they have to take Brady back unless Cassel gets a superbowl win there's no question there Brady has to come back the patriots are not the same without him ........... but why to chose I say lets keep the two jajaja

Yes I think that Brady has to come back I don't think that Cassel be the answer for the Patriots, just look at this season.

of course tom brady, cassel is an excelente QB but he don't the experience of tom, tom has won the superbowl, became the mvp, the offensive system has been created specially for him and I think in the netx season we will see again the big bazooka tom

It would be sad to see Cassel go though.

Sure it is, Brady has to come back!! he's the best, 3 superbowl champion, Cassel is good but not too much as Brady.
"but why to chose I say lets keep the two" <- Not doubt hahaha
