The Steelers' complicated zone-blitz schemes and ever-varying looks are troublesome to the league's top quarterbacks, so sending out a player who has yet to throw an NFL pass to oppose them would seem to be a tremendous mismatch.
That's why some of the Steelers (3-1) are questioning how much they will actually go against McCoy, if he's chosen to start. They recall how the Browns upset them 13-6 in December, effectively deploying Joshua Cribbs in the Wildcat offense during a loss that contributed to the Steelers missing the playoffs.
"Given that we might be facing a rookie quarterback and that we do confuse people who have played football for a long time, it would seem to be a mismatch," Steelers safety Ryan Clark said Wednesday. "But look at the game last year, when Brady Quinn started. They ran the Wildcat most of the game. They ran the ball and were able to keep the game close enough so that they never had to get out of that game plan."
Cribbs also has three of his eight career kickoff-return touchdowns against the Steelers, including a 98-yarder in Heinz Field last season.
"He's got great speed and agility and balance," Steelers coach Mike Tomlin said. "He's uniquely powerful for a wide receiver-like guy. He's extremely tough to tackle, he's strong, and he's highly conditioned. Anybody that covers kicks, returns punts, returns kicks and plays offense is a highly conditioned athlete."
The Arizona Cardinals appeared to be in deep trouble when they started undrafted rookie quarterback Max Hall on Sunday against the Super Bowl champion New Orleans Saints. But Hall held his own by completing 17 of 27 passes -- 9 of 12 in the second half -- for 168 yards as the Cardinals turned a succession of big plays by their defense into a 30-20 victory.
Arizona had the benefit of playing at home, but the parallel exists between Hall starting against New Orleans and McCoy potentially starting against Pittsburgh.
"It definitely opens your eyes that on any given Sunday ...," Clark said. "Arizona's defense played a whale of a game and kept the game close enough to make plays at the end. We want to get up early, because if we get up early, Colt has to come to us, and that's what we want."
"That game last year would be a good game for us to watch and understand that they have ways of making plays without the quarterback having to make tough decisions and tough throws," Clark said.
"He's got a tremendous opportunity to start off with a great story," Polamalu said of McCoy. "We have all been in those situations where we've been underdogs or been favored, and it doesn't turn out the way everyone thinks it will. With all the lessons we learned in the past, we could have our hands full."
