Portis is a great back, but why do you play Portis if he is not 100% and the backup back plays just as well.
This is the problem, unlike other teams with 2 RBs sharing carries the Redskins are setup traditionally with Portis and Betts, as a starter and a backup, both need carries to succeed.
Until Portis is 100% he does not go, the back which practices with the first team during the week is the back which plays.

Betts is the better back, now! why is he not playing?
 and of all the teams the Redskins must have the uncapped year to get rid of all the “dead weight” which prevents the true overhaul which is needed.

Let’s not discount the practice factor. Betts has practiced with the line all week the entire year. Obviously, the line still needs to open the holes, which they haven’t necessarily done with Clinton, but when they have Clinton hasn’t been there.

What I’d love to see is Zorn not playing Clinton until he has a full week of practice. Whether that happens, we’ll see.

Maybe healthy is a relative term- maybe Portis has enough mileage that he just won’t be “healthy” again. Maybe, though Betts is two years older, he is, in fact, younger in football-years.

Or maybe what we’ve really learned here is just the value of fresh legs.

I think that what we should take from this is that the 2-back system most of the NFL has switched to is more effective because carrying the ball 25+ times a game destroys you, like it is destroying Portis. Betts and Portis will BOTH be more effective if they are splitting carries, otherwise I think that we’ll see the 30-yo Betts wear down even faster than Portis has.
