ive been wondering the same thing, although i wont use the word "elite", more like a top tier RB... Elite is reserved for players that have proven themselves for a few years.
I have a feeling that Morris will be a solid player for years to come. I picked Morris up in both leagues i play in right before the start of the season, he was undrafted in both leagues. After watching him all season, i feel that he has the potential to becoming one of the top five backs in the league.
here are just a few stats... week 17 stats has been excluded...
Morris comes in 4th in rushing yds with 1406, just behind AP(1898), Lynch(1490) and Charles(1460).
Put up 10 TD and averaged 10.9 fantasy points.
If Morris can maintain these stats, which i think he will as well as improve on them, than i believe he will fall in the top tier of back int he next few years.
As for his value next year, id say he'll fall between 8th and 11th overall for his position.
