I think the biggest red flag on Jackson (and there are several) is that he didn't want to go to a team where he had to compete for minutes.
Really bruh? You want to be known as this ultra-competitor, alpha-dog, but you're 100% willing to sacrifice your draft position and money so that you don't risk having to outplay your teammates in practice for your playing time?
Sounds like he's all done working hard to me.
