Assuming no new free agent comes in (in addition to drafting a QB), it doesn't hurt us to give Trent a chance to win the job.
If he squanders his chance again...well then he's gone. But how crappy would it be if we didn't give him a chance, he signs with someone else, and becomes the next Drew Brees? ..of course that is an incredible OVER EXAGGERATION but you get my point...hopefully.
