Archer is saying only 200k guaranteed now, so looks like you were right. This is not a bad contract at all. Very low risk, for what could be a high reward if he can stay healthy.
The money is actually not the issue.
The risk is the complete waste of time and resources.
Dallas needs a proven veteran back AND a 1st or 2nd day RB in this strong RB draft. This turd makes Dallas think they've already addressed their veteran RB need when he's 95% going to be cut before the season.
Suppose Gurley somehow falls to Dallas in the 1st. It's the right long term value pick and probably makes a huge impact for years to come, but he won't contribute at all in September. A veteran back plus Randle and Williams address that risk.
Spiller or even Mathews would have been perfect.
