This is kind of like asking what do you call a dog that has no legs - doesn't matter, because it won't come to you anyway.
The same with this QB position - it really doesn't matter because the offense as a whole is inept anyway. Starting at the QB position, Grossman is a QB that has brilliant flashes surrounded by waves of inconsistency. Whether this has to do with inexperience due to spending the first half of his career on IR or not, doesn't matter - he hasn't performed as of yet. As far as Orton - he's just a bad pro QB. The second half of the equation is the offense is just as bad as the QBs, but doesn't share the same amount of the blame. They have no RBs or WRs worth speaking of an dthe O line doesn't do their job in protecting the QB. And people wonder why it doesn't matter who they throw back there at QB, they look ridiculous...
