The Cardinals have a pair of obvious focal points on offense heading into 2018: elite running back David Johnson and star wide receiver Larry Fitzgerald.

After an offseason of work with new offensive coordinator Mike McCoy, wide receiver Chad Williams believes the system won't be overly reliant on the two stars.

There is an intriguing second tier of options behind Johnson and Fitzgerald, which includes Williams, wide receiver J.J. Nelson, tight end Ricky Seals-Jones, wide receiver Brice Butler, running back Chase Edmonds, wideout Christian Kirk, tight end Jermaine Gresham and running back T.J. Logan.

"You can get hurt by anyone in this offense," Williams said Thursday on the Big Red Rage. "Backfield, tight end, split all the way out wide. You just don't know what you're going to get. You have to be on your toes. You don't know where you can get hit from. It's like fighting a guy with eight arms."

The Cardinals were obviously hurt by the absence of starting quarterback Carson Palmer for a big chunk of last season, but inconsistency among the skill weapons beyond Fitzgerald was another reason why the offense struggled.

McCoy seems willing to spread the ball around provided the other options prove capable.

"He just wants to win, so whichever way he has to win, I believe that's the way he'll go," Williams said.
