Funny. They said the same thing about Melvin Gordon his first year in San Diego. Not saying those things now.
I guess its real cool to make dramatic proclamations, ignoring all facts, and then stand on your high horse when they come true or slink away and never mention you were an idiot when they don't. But calling a rookie a bust after 8 games is pretty out there on the stupid scale of fandom.
Maybe he'll be a late bloomer, maybe he won't but none of us can be sure at this point. Admittedly i'm a bit concerned he'll never be the player we want him to be but I've seen many a player turn it around in this league that the bust thing is uncalled for.
Just looking at the Seahawks: Alexander, Lynch, Hass, Chancellor, Britt, Sweezy, Ifedi, and probably a whole bunch more took a while to figure the NFL game out and were not world beaters in their rookie years (or even second years).
The expectation that rookies immediately figure it out has never held up to scrutiny. Some do, Some take a while and many never do. That is why drafting is such a crap shoot. But you have to accept some guys take a bit longer.
