We'll find out in 3 years if it continues to be a big deal to you.
In 3 years, it will be time to pick up Maye's 5th year option. Either he'll be great and have already have signed a long extension, or we'll be on the fence about picking up that option year, which would be disastrous.
Either Joe Milton will be a backup on yet another team, or he'll be the starting QB of the Dallas Cowboys.
It's all about performance now - none of it is conjecture, or potential, or wishes and hopes and dreams anymore. That's what Vrabel did with this trade. He absolutely did not have to do it, even if Joe Milton thought he was the best QB that ever QB'd, he's still under a cheap contract for two more years.
It might not *feel* like a big deal, but Vrabel made Maye the unquestioned starter with no competition going forward with this deal. That *is* a big deal, when you have competition already on the roster for basically nothing.
