‘Asked if he could return to full-time duty after settling into a speciality back role, Thomas, 33, said he’d do it but warned he’d be shot by mid-season. “I’m not ready to go back to full time,” said the man who is ninth on the NFL’s all-time rushing list with 11,786 yards. “I like the role I’m in, not all beat up and unable to practice until Thursdays. “If I have to play full time, go 60 or 70 plays, I’m ready to try early in the season but once it gets late in the year, I’d have to cut back and rest. It’s just because of my age and I’ve been hit so much in 12 years. It’s just the way it is, like a Marcus Allen.”‘
