BWP, same thing. He had played in the Championship, but was only ever successful in League One.
I mean, that's not really true. He was good enough to get 32 PL appearances and scored at a mediocre rate in the Championship. He succeeded in League One.
This guy peaked in League 2 and has been basically irrelevant in the Championship and League One.
To say they both played in the Championship and League One is like saying Rece Buckmaster and Kyle Duncan are both MLS players. That's technically true, but they're at opposite ends of the spectrum.
