From some of the Atlanta games that I saw, he did a lot of dink and dunk passes, but is mobile enough. Minshew is better, but he's in Indy now.
His replacement, Taylor Heinicke says that Atlanta told him when he was talking to them that he was to be the backup to Desmond Ridder.
Also, I could see Kansas City signing a veteran free agent. They need to replace two time Super Bowl Champion Chad Henne. Matt Ryan seems like an Andy Reid type of QB, but he may not want to play anymore.
