Some of you people are either really dim or just completely ignorant.
It isn't about McPherson being better or worse than Rosenfels. Of course Sage is better at this point. He has been in the league for like 4 years now, while McPherson is a rookie, and one who didn't exactly get the full college career before that.
None of that changes the fact that McPherson has more talent and tools in his index finger than Sage possesses in his entire body. Wake up and realize that Sage isn't going to get significant playing time no matter what. I do think Sage could be a serviceable QB if ever given the opportunity, but he has pretty much reached his ceiling as far as progression goes. McPherson can potentially get much better, and Sage can't. That is the bottom line, and there is no reason to just keep Sage buried at #3 when he isn't going anywhere, playing time or developmentally.
I know the concept of actually developing a QB is really foreign to all of us Dolphins fans, but look around the league. Almost every team's 3rd QB is a really young and raw guy that is there strictly to see what he can become. With the Dolphins, for years it has been just basically a body to have in case of emergency.
It would be a really solid move and forward thinking if they did it. If he doesn't pan out, big deal. That is why they are late round picks and buried on the depth chart to where they don't see game action.
Doesnt change the fact that if someone put them thru Drills Adrian would make Sage/Brock look like peewee players.
