To many, if not most Cowboys fans, it seems to me that they'd be interested in seeing how Trey Lance performs, once he is tested by this team. It's certainly no secret that his rating among most NFL fans isn't one that sparks images of a QB who has impressed the teams that have signed him for whatever reason.
As far as the Cowboys are concerned, he represents an expenditure of a 4th round draft pick and that's all. In all honesty, that's hardly enough to inspire confidence in his ability nor his worthiness to bear the title of a respected NFL QB at this point.
I'll be intrigued to see exactly how this situation with him does or doesn't bear fruit. Obviously, Jerry and one or two in his staff feel it's a worthwhile venture that they've investing in with a somewhat paltry 4th round pick. To be sure, it remains to be seen how this thing develops for most of us. If Lance eventually develops into a reasonably capable backup, it seems possible that such a 4th round pick wasn't something given in vain.
