didn't ricky quit after a 395 carry season? portis loves to play, but at that pace, maybe he won't love it quite as much
part of the problem was also that the blocking wasn't as good as it could have (should have) been, so he probably took more big hits than he needed to, which obviously wears you down faster.
I'm also hoping betts can start carrying it a little more, and that our receivers can get together with brunell and work through whatever issues they seem to be having...
