Cassel is playing well for the most part up to the 1st drive in the 2nd half. He made some good throws and decisions, but the 3rd down before the missed FG stuck out to me.
Look how far up the circled safety is on this play. Before the ball is even snapped the safety is creeping up, thus leaving an all-pro WR 1 on 1 on the outside. Why don't you throw it up to Bowe and give him a chance to make a play instead of trying to squeeze one in between 2 defenders? He already has a step on the CB. I get that it's third down and you want a completion but Dex really isn't that open. The circled safety would have drilled him even if he had caught the ball, he ended up closing in quick. He ends up staring down Dexter the whole play and the ball ends up getting batted down by the LB in the short zone and the missed FG leads to the quick demise.
