Absolutely, I've learned a lot about quarterbacks from all the members of the Henne brigade around here....
You can't coach "clutch", tay.... being put in a better system doesn't make you a better quarterback, it only makes for a better environment...
Henne still has to make the plays when they matter, and I think Miami is still going to need a legitimate upgrade at the quarterback position. However, this has the potential to keep everyone involved from looking completely incompetent and embarrassing... I wouldn't bet on a hellof a lot more than that.
