I made a cfm and my team is the Jags, and i'm confused aboutwhat all the traits in progress player mean. Like for my dbs should i upgrade the play ball trait? Should i even bother with the traits? I upgraded one of my DT bull rush move from enabled to no, did that do anything? And i have enough xp to upgrade it from no to yes but it's locked do i need to up some other stats before i could get those types of moves?
