It was rumored that Fox wouldn't play any summer league games at all.
I think the Kings probably put the old guilt trip on him to play at least the 1st game of the inaugural California Classic, to give the fans a show and something to get excited about.
All in all, Fox looked really good. He has definitely gotten stronger. He needs to work on his body and his 3 point shot this summer and he should be ready to take a big step forward next season.
BTW, you can see how much better Bagley and Giles looked with Fox running the show. That is what we should look forward to this season!
