big PJ Carlismo fan there???
IMHO: Pop is top 4 right now (with PJ, Red, Riley)...Problem with him is, that up to this point he linked his carreer to Timmy. Ok, its not like these other guys had no great players/teams, but what we need to see is, if Pop can do a good (not even a great) job without Timmy.
Get a post-Timmy team to the playoffs...get a team without Timmy to be called a "fringe contender"...its not like he needs to win another ship (the others didnt without Superstars either), but we need to see some years without this one guy.
I would choose him, if there was an All-Time-Draft and I had to pick a coach, but if his carreer ends today, everyone will recognize Timmy+Pop, Timmy for himself, but probably not Pop for himself (not to the point the deserves).
