Williams can't afford average anything after the assessments all across the scouting world calling him the best college passer to come into the league since possibly Andrew Luck in 2012. If he can't afford it, neither can the coaching staff.
The possibility Williams will struggle through his rookie year won't even be considered here, as it might be enough to set off some sort of national Bears fan panic.
At this point, there is no need to think worse of him, though. Then again, he hasn't been facing a live NFL pass rush.
"I think that Caleb is a talent, a very good talent," Bears coach Matt Eberflus said. "His game will go to where it needs to be."
So far they've had him going against the first-team defense most of the time at minicamp and OTAs, or at least the first-teamers who are available. It will continue next month at training camp.
"I want him to see that in front of him, the windows closing, the variation of what we do on defense, and I want him to see that day in and day out so that when he gets to play somebody else it will look, 'OK, I've been there done that,' " Eberflus said. "That's how we're going to keep it.
"He's done really good. He’s progressed all the way across and hit guys. He's progressed to open spaces in his first two progressions and dotted guys. I think it's been really good."
It needs to continue when Williams arrives because a coach in his third year of a rebuild, without a single winning record, is in a precarious situation. Logically, Eberflus needs the wins and a defense is only going to get them so far.
