On Patriots 5th Quarter and Belichick's press conference, he actually had unequivocal positive things to say about Cassel. He flagged him as having a really good week of practice and noted that that usually carries over into the game. When asked to name a player who really showed up well, he didn't hesitate in saying that was Cassel.
We have obviously not been able to really judge whether good performances from Cassel starting with the Miami game are all that indicative or judge whether his problems are symptoms of shortcomings.
But this game I think does set a benchmark that we can actually say this guy looks pretty good and may be a really solid backup for Brady. It is, of course, still very much a preseason environment, but he looked like there is a good chance that he has IT. Pretty good feeling.
