That's a pretty huge if on Pena. If he does, then yeah. He's impatient enough for the quality to change his entire game. However, one has to hope that his Dunn-esque BA turns into a Guerrero (or slightly below) BA and his other stats go up accordingly. At this point, to an outside observer, they are both players with
A) Low BA
B) Big Power
C) Lots of K's
That doesn't mean WMP wouldn't turn into a different player, but I'm willing to believe that many people (not necessarily GMs, but consider who they have to please usually) simply see it hat way.
