I just finished grinding for my two Yao's PG and C, I feel like I didn't come away with any cards. I wanted PF Shaq instead of PG Yao, because I heard so many wonderful things about him I pulled the trigger for that card. I had GT Melo, he is hands down the best PGs I've used all season not including one of my favorite players. Long story short I am not using either player and I feel like I made a huge mistake. Hopefully we can sell the players in the future, right now I did so much grinding for basically nothing.
