Did you watch him play at all last season (not trying to throw that out as the typical board insult)? He looked very explosive and showed quick feet for his size. He is more of a "power back" then a slasher like Shady, but I would disagree as to him not showing that he could be a starting RB or a threat to Shady - and I have no bias as I am not an owner of any part of the Buffalo offense.
I will say that he does run upright, since he's 6'1", so he does expose himself to big hits and was constantly banged up last season - so in that regard maybe he would struggle as a full time feature back.
Bad news about the suspension.
Bills' Karlos Williams suspended four games
http://www.nfl.com/news/story/0ap3000000675000/article/bills-karlos-williams-suspended-four-games
"The
Bills hoped Williams would reprise his role as a smash-mouth accompaniment to
LeSean McCoy. As a rookie, Williams earned 517 yards on just 93 carries (5.6 yard per tote average) and seven rushing touchdowns. Among all players with 90-plus carries last season, Williams had the second-highest yards per rush in the NFL in 2015."
Serious question - What percentage of the time does a four game suspension signal that a player will soon be out of the league? Dunno.
As to his talent and potential to be a feature RB, imo it is important to remember that, like Jeremy Langford, A) he only played RB two years in college and B) he was one of the fastest RBs at the combine. He could have upside and improve with pro positional coaching. He is clearly a gifted athlete. As a prep, he was ranked by Rivals the #2 safety in the nation and a top 10 overall talent at any position. Not an exact analogy, but it might be similar to if Calvin Pryor, Landon Collins or Karl Joseph switched to RB in their last two years of college. It is to be expected there would be some adjustment. I think Langford ran a 4.42 (fastest among RBs in 2015) and is listed at 208 lbs. Williams ran a 4.48 at 230 lbs., which weight adjusted, is pretty freaky. How many 230+ lb. RBs have cracked 4.5 in the past decade, it could be a small list. I wouldn't say he has great phone booth quicks, but he isn't just a straight-line stiff, either, he is at least a one cut runner with some contact balance, COD ability that presents a dangerous size/strength/speed combo in the open field (and on the bonus plan, appears to have at least decent hands).
Buffalo Bills RB Karlos Williams can set an NFL record on Monday Night Football 11-21-15

"In his first six games, Williams has found the end zone seven times. He's scored five times on the ground and has two touchdown receptions over the six games, and at least one score in each game. This currently has Williams tied with former Patriots running back Robert Edwards for most."
So despite limited experience at his position, and limited action, he had one of the best averages in the NFL, and tied an NFL rookie consecutive game scoring record. In both instances, something nearly all STARTING RBs never come close to. For me, he has intriguing, if not compelling talent, and I'm interested to see what kind of follow up he is capable of if he can get his act together and in shape. The sub-100 carries is a two-edged sword. He is relatively unproven, but it makes me wonder what kind of production he could have had given an expanded role. Are there really 32 RBs in the NFL with superior athleticism, measureables and pure rushing ability than Williams (to be fair, different ways to define starting caliber talent, maybe there aren't necessarily 32 at any given time, and those that are CURRENTLY counted among them, may not be for much longer, either)? I think it is at least an open question, for me the answer isn't obviously yes. And that is NOW, not factoring in potential improvement.
For practical purposes, McCoy is the starter for now, and possibly for a few more years, making Williams more of a long term dynasty play (unless he gets a bigger RBBC complementary role, not off to a good start in '16). But McCoy turns 29 before next season.
