No, it isn't wrong. I think it's a sign of objectivity and maturity when a fan is willing to acknowledge and show respect for opposing talent. It's not like you have to be a "fan" per se but you can still respect them. It would be nice if this or other threads showed more of that mutual respect from time to time, rather than yet another HF pissing contest.
Like I said the other day, there will come a time when you will miss the players that you used to watch after they're retired, even the ones on the other teams as well as yours.
