It's about the money, not the player. That's not the only choice considering this team should have a shot at one of the blue chipper (cheap) QB's and take that risk.
One major error some are making in their thinking is that this brain trust can do better than Prescott at QB, since he was all luck, and that they'd use the savings to build a better defense. If the latter is the case, why haven't they done that? Why didn't they do that with Romo?
The assumptions is that it is only money, cap, that is keeping these people from building a true contender. Does anyone here really think that?
If you think they couldn't do worse than Prescott, you have selective amnesia. This franchise is one of the worst and most luck dependent ones with that position in the league.
The thinking, get a cheaper QB and have a better team, is flawed. Mistakes with other players/positions have already been made and only time will address that.
