Don't forget to upgrade all your players

I didn't realize this until today somehow lol 

But, you can upgrade ALL of your players, not just the ICYMI / SOTW / Legends / UA players. 


Every player can be upgraded once and a lot of them will gain traits once you've upgraded them. 

You can get the Training points you'll need by selling off all your low level players who aren't on your depth chart.

The game never explicitly tells you this, other than leveling up players like Nic Scourton and having player traits can make a big difference
