I don't think he is worthy of a rb2 ranking.
Rb3 or lower is where I see it.
And there is no way I would draft a rb2 thinking that he might hold up for three or four games, that's to much to spend.
I see it exactly the same way you do, and for that reason I see him a rb3 or lower.
I dont think he has fallen that far.
But to be honest, its likely too early to make that evaluation. With a year out of football, I'd like to see him play a bit in preseason before deciding where I'd rank him in the end.
There are some pretty weak RB2's out there and I am pretty sure Lynch is better than they are. I really dont see too many drafts where Lynch is drafted as a RB3 at this point in time.
That being said..... IF (yes that's a big IF) Lynch looks absolutely awful in preseason, he will quickly turn into a DND or a low end RB3.
if he looks good, I'll get him as a mid to late RB2(if I can) and be happy with the value.
