For most of Mike Wallace's four-year career with the Steelers, coach Mike Tomlin would refer to him as a "one-trick pony." In the beginning, you got the sense Tomlin was serious; Wallace was really good at one thing: running go routes all day long as defenders were helpless to do anything about it.

But Wallace went from running fast in a straight line to showing some mastery of the rest of the route tree (see the pitch-and-catch-turned-51-yard-touchdown against the Giants last season as proof). Still, "one-trick pony" stuck even as Wallace signed a five-year, $60 million contract with the Dolphins hours into free agency.

That doesn't mean it's true, though -- just ask Wallace's former quarterback, Ben Roethlisberger.

"Mike is way more," Roethlisberger told TheFinsiders on Thursday. "It's to Mike's credit. Mike is really focused on becoming a better receiver. So he's focused on his route running. He's focused on running out-routes, and curl-routes, and in-routes and doing all the little things that's required to become a great wide receiver. That's why he, to me, is one of the best in the league, because he not only has that speed -- he can run by anybody -- but he can (run) routes and he can get open."

In four seasons, Wallace totaled 235 receptions for 4,042 yards (17.2 yards-per-catch average) and 32 touchdowns. But an inconsistent effort in a new offense in 2012 (64 receptions, 836 yards, eight TDs but with a 13.1 YPC average and catch rate of just 54 percent) made it easier for the Steelers to let Wallace hit the open market last month.
