Based on what?
The fact is that 31 teams could have , and didn't.
Bear that in mind.
The Cowboys cut their "#2 quarterback" because they knew nobody else would touch him. To keep their "#3 quarterback safe.
That's not 'shrewd maneuvering', that's an indictment of your decision-making.
Good gosh, dude.
Dallas has a promising young lad in Cooper Rush. They aren't going to expose a player with potential WHO MAKES ABSOLUTELY NO MONEY to free agency. Any team could stash that on their roster with no risk whatsoever.
Meanwhile, Kellen Moore is a run-of-the-mill career backup guy, just like Jason Garrett was or countless other guys. He's smart, and
he knows Linehan's offense frontward and backward. No team wants to replace what they have with another guy who doesn't know their system. Teaching a QB a system is a long process, even for veterans.
It's not a surprise nobody signed Moore.
And what I don't understand is why nobody sees that this is just a temporary situation until Rush is ready to run a real NFL offense in a real game. He's never read a defense in his life.
