If Jr returns to form (and I think he will), would that qualify?... or would that be listed as "Comeback Player of 2003"?
But if I can't list Jr, then I will go with Austin Kearns. He is the real thing IMO.
Close your eyes and imagine that scene from the Wizard of Oz where the Cowardly Lion is chanting the mantra.... "I do believe...I do believe.... I do...I do...I do believe"
