Somehow, I managed to foul out Perkins while playing the challenge, which forced Irving and Hayward into the lineup.
As for Nique, it's your choice if you want to sell him. Personally, I run Nets Erving, LeBron, Barry, and occasionally Drexler and Simmons as my 3's. All can do the job I look for. I'm debating if I want to get Pippen again, especially since his dunk package has been corrected, but on the other hand, I'm also comparing the attributes with All-Star LeBron, and he looks like the better offensive player. Sure, Pippen has a 99 defense, but I don't think that really matters since James swats shots left and right, and he doesn't even have a 90 defense.
Mikan turned out to be a fun player to use! Like Mutombo, he's a valuable card to have despite having lower than average overalls for a center. Plays great defense, he's not too slow, and he's a pretty good dunker.
