Dalton went into a tailspin the last half of the '11 season losing more games than he won once the film was out on him. Through his pro career he's beaten a scant few winning teams. Because he wasn't a first round choice (deservedly not) and a ginger ESPN over-hyped him as one of their Poster Boys. If he didn't have Green he'd be a bottom-tier QB. Personally I'd rather hitch my wagon to Tannehill and his upside than Dalton's.
Wisdom from a "QB Whisperer::
"No we have our FRANCHISE QB and I want to keep him rather than get 2 guys who may or may not be productive NFL players.
Palmer's situation is different and if I had my choice between Palmer and buttfumble, I'd take buttfumble"
