Espn also reported 8M so that's probably the true number. I was surprised to see him signing for 1.4M as he earns way more than that in China.
Considering how much lakers is paying Mozkov, 8M doesn't look so crazy. They'll probably get their money back off court anyway.
Yi is not a bad player, his problem is he never know how to be a good role player, but he's not good enough to be a star, not in NBA level. Not sure how is he going to work out this time
