So we have come to accept that Jenkins and LMJ will not be used much this year, but it could still work out to being a great draft. However, I think it would be safe to say that we would view it as a mistake if they are not used next year. However, they will have the same issues next year, and must unseat a veteran in order to get on to the field - or that veteran needs to leave the team.
I think a lot of this depends on LMJ learning to field punts. If he can learn to do that, then we can let Ted Ginn go, and LMJ and Kyle Williams could handle punts in his place. Having a place on special teams would also make it easier for him to get on the 46 man roster. So with this in mind, I see the following happening:
Randy Moss and Ted Ginn do not return next year. This will ensure that Jenkins makes the 46 roster. He can then compete for one of the 3 starting positions.
Brandon Jacobs does not return next year. But even with this move, LMJ will not make the 46 unless he can play on special teams, or unseat Hunter as the #2 RB. I think he is going to have the hardest time getting on the field, other than possibly special teams.
