At worst he's a guy that you quickly learn is a far, far worse option than Cooper Rush, and never plays a meaningful snap in Dallas....ever.
That's the worst case scenario.....and based on history, probably the most likely.
Busts don't usually become good #2's....much less a starting QB. We will see.
How can he be a bust when he has barely been in the league and am injury derailed an entire season?
Not every player comes in day 1 and produces at a high level. QB takes time, some more than others.
Sure he can turn out to be a bust but his ceiling is a franchise playmaking QB. He has all the traits, just needs the developing part. Spending a 4th round pick on a QB that just turned 23 with the potential of Lance is a very good choice. If he bust you lost a 4th round pick which odds are you aren't getting a starter with that pick anyways.
It's not like Dallas gave high picks for Lance. Just a 4th rounder
If you can't see that, then I will just respectfully disagree with you.
