I still think the Lance trade was probably worth making if the intention was to try to develop him into something they could trade for a higher pick. But I never thought this was anything more than a long shot. SF already tried to develop him and failed. He could not beat out Sam Darnold. When he plays he looks as bad as the garbage the Cowboys tried to use to take Aikman's place. He is worse than Quincy Carter. How long should it take to develop him enough that he can at least look like an NFL QB? How much time does Dallas have?
At this point, they will probably cut him or trade him for a 7th, a conditional 7th. But more likely he gets us nothing in a trade.
This doesn't mean I wouldn't play him the rest of the year. The Cowboys still think they can win some games and do something. They are delusional. I think the season is over so why not play Lance. It's not like Rush has something to prove. We know what he is - a mediocre backup. But I'd play all the scrubs as much as possible and give them real experience. The Cowboys need to start churning the roster and that means finding out who is worth keeping. You cannot make an upgrade unless you know what you already have.
