"Johnny is a real impressive guy," Shanahan told reporters Thursday, per The Plain Dealer. "I don't think everybody knows really what Johnny is about, and Johnny is very humble. Johnny is a real dude. He's not going to sit there and BS me or anything. We all were embarrassed by that game."
"Anytime you don't put up points -- it's not just Johnny -- all of us are extremely embarrassed about that," Shanahan said. "We want to get back to Sunday, and Sunday couldn't come quick enough."
Shanahan dismissed talk that Manziel is embarked on a three-game tryout for the starting job, citing "lots of quarterbacks around this league who've been playing for five years that people still aren't quite sure about."
Shanahan isn't ready to think that way, though, telling reporters point blank: "I feel the same about Johnny as I always have. Johnny is a playmaker. He's done that throughout his career. Nobody can argue with that at all."
