Morris missed four games with a knee injury he suffered against the Titans last season. He ended the year with two touchdowns, 319 yards on 73 carries during the regular season.
When the group is healthy, Morris said sharing carries helps with longevity for everyone.
"Even for a younger guy, I don't think that they could just continue to take the pounding like that especially in a physical position but that plays a factor and after that the onus is on us to take care of ourselves," Morris said.
Diet and conditioning play a large part in staying fit throughout the season, Morris said. He isn't ready to put a timetable on his career just yet.
"I just keep going and going," Morris said. "I don't want to get to the point where I can say I can play two more and shut it down after two, when I actually could go more. I'm just going year to year and right now I still feel pretty good."
