I've got LJ too..I'm not worried at all about Priest coming back or not..Cmart let the league in rushing last year, and Lamont jordan had a good season in a backup role..I look for LJ to get 1500+ yards, and for priest to put up about 300-400 yards on less than 100 carries..this is a conservative estimate, I think LJ could do 1800+ yards easily..
Apples and oranges. Jordan didn't have a couple of the best seasons ever for a RB on his resume. Priest does.This is also different because Martin was the respected, older veteran, who Herm gave preference over the younger back with great potential. This situation is the opposite. I'm not saying Herm won't feature LJ. I'm just saying that I think Herm is the type of guy who respects talented veterans, and I think this makes it more likely he will find a non-trivial role for Priest if he comes back.Also:Last season

riest had 7 TDs on 140 touches. 1 per 20 touches.LJ had 21 TDs on 369 touches. 1 per 17.6 touches.Last season

riest had 4 TDs on 7 rushes at the goal line.LJ had 10 TDs on 24 rushes at the goal line.The year before, Priest had:10 TDs on 18 rushes at the goal line.15 TDs on 215 touches.Both of those were better than LJ's performance last season.LJ is great at the goal line, but I don't see compelling evidence that he is significantly better than Priest. I could easily see Priest taking at least some of LJ's goal line touches, as well as some touches in passing situations and/or in the red zone in general.
