Don't know for sure. But you can read between the lines. Novak coaches a motion offense with everyone involved. He said on his post game conference yesterday that whomever has the ball becomes the point guard. The way the team is sharing the basketball with each other kind of hints to the fact that Rickea did not agree with that strategy. So, in some games, she just stood in the corner when we needed her to be more vocal with the team. I think that Vic also saw this along with Mingo-Young, Matharu, Madison Hayes, etc. You get the picture. It is very hard these days to coach a diva.
If Jackson really balked at running a motion offense, that was really short sighted. A well run motion offense still features the best offensive player, it's just more likely to get him/her the ball in scoring position with help defenders occupied chasing their man and/or helping off picks. It is hard to execute at that level and when it's not being executed well can result in a lot of possessions where the best offensive player barely touches the ball or doesn't even touch the ball at all, but it's really fun to watch when it is done well.
"Let one of those 4 or 5 stars not do what he says or do what is best for the team and see what happens to him." I tell you what happens, the 5 star behind him steps up and he takes a huge pay cut.
