I agree it is obvious, but I'm not going to stop caring.
Character matters and should matter. Context also should matter.
Rose is an absolute scumbag and serial liar. He should never be celebrated by the Phillies much less put on their WOF. That is deeply embarrassing. Yes, he was part of the great 1980 team, but his actions and behavior since have long over shadowed such glory unfortunately in my mind.
Thome is not only a total class act, but does have important Phillies history on his side. Prior to his arrival via FA, the Phillies were the dregs of MLB. They'd had 2 winning season in 16 years. They had a deserved rep for not caring about winning and being cheap, fielding teams that had a chance to only play out the string and fill the owner's pockets. The new stadium opens, Thome signs and a new era was born that eventually led to the run from 2007-2011.
I see Halladay as a class act as well, but his place in Phillies history is a stretch imo. He came onto a dominant team after they had already won a WS. There was no new era, in fact the move to bring him in helped kill that era imo because it helped locking the Phillies into not facing reality and rebuilding sooner.
