Something about Lynn just seems extra combustible too. I'm not sure exactly what it is... body, stuff, mechanics, statistical profile... Kind of hard to put a finger on, but I definitely wouldn't want to trade a position player under 28 of equal talent for Lance.
It's also not impossible to see him getting bumped to the pen at some point, even if he's pitching well. All it takes is one or two bad months of batted ball luck, and then he could be looking up at five names on the Cards' stacked depth chart. He's always kind of "looked" like a reliever in a lame scouty way, anyways.
