Portis staying?

[Beneil (diehard since 87)]

Even the best or runningbacks stumble. Peterson just yesterday did the same thing and ended what was one move away from being a 50 or 60 yard td run. Betts is a mediocre back-up at best. The only time he was worth his weight was when portis was injured, randy and samuels returned, and Betts had the full and healthy o-line ahead of him.
Seriously though. I mean, yeah, Sellars had one year were like 8 out of his 9 catches were TDs but since then, what's the situation? He's costed us many games where there was no if, ands, or maybe's. I'm sure we ALL remember the goaline drive where he literaly handed the otehr team the ball. We cant use him as the power-back in the redzone cuz he fumbles too much! and we've tried, lord knows we tried, but he never busts threw for the touch, but PORTIS does. (so does Marcus Mason)
Now, If Shanahan can find another YOUNGER Champ Bailey to trade Portis for, then fine, but the LAST thing i want is Portis to run uss over like Stephen Davis did when we let HIM go.
