Mixon's age is irrelevant when he's a RB. Have we not seen countless great RBs run into the ground with heavy workloads and retire early despite how good they once were? There's a reason "tread on the tire" is a common phrase when it comes to RBs. Look at Arian Foster - He didn't even make it to 28. Age just quite simply isn't an indicator of how long a RB can keep going like it is for other positions. He's apparently stayed moderately healthy so hopefully that's an indicator that he can keep going strongly for at least a few more seasons - I just wouldn't rely on it.
They basically did cut him and informed him he was being cut. Except when the Texans found out they offered a trade to the Bengals so the Bengals reversed it and dealt him, happens every so often.
Mixon really isn't a top gamechanging back in the league and never really has been imo. He's been a steady really good back but he hasn't been at the level of McCaffrey, Henry, Jacobs, Chubb, Taylor, etc. He's never been a back that just makes the team have a dominant rushing attack. 1000 yard season sounds great and all, but to be blunt he's a borderline 4 yards a carry back and has been for quite some time. I'd like someone who can get more than that but that's just me. I do appreciate his ability in the passing game though.
And this is all to say I like Mixon. I think he can help us with some glaring issues we had last year. Things like 3rd downs, 4th and short and general short yardage situations as well as red-zone running. I just don't think he's a big enough difference maker to be able to overcome the lacklustre run blocking from the team and I don't think having a heavy running attack is in our best interests considering CJ and this receiver corps. In fact I hope Bobby changes up some of the play calling because we led the league in run, run, pass play call sequencing.
