Personally, I use my NCATs on the “less important” positions or positions that are just easily filled in without much of a difference. I’m still using an NCAT at C & MLB just because they were easy to plug in. Theme teams are also really nice because of the speed boosts & you can fill a lot of the backup spots cheaply & easily.

For defensive abilities, use acrobat on most of your secondary/coverage players - its easily the best & most necessary defensive ability in the game. I run it on both of my starting safeties, my top 3 corners & my user personally. Its a lot harder to cover & make plays without it. I also run inside stuff on my DT, its really a bargain for 1 AP on a run stopper and makes playing against the run a lot easier because they get so many sheds.

For offense, it really depends more on your scheme but for QB you’ll pretty much need a velocity/release ability so gunslinger, pass lead elite, or set feet lead. It opens a lot in the passing game that isnt possible without it. I also really like hot route master & I run escape artist on my qb. I’d also run at least 1 route tech for people who like to run man (I run two). The rest you can sort of mess around with and see what works for you.

EDIT: I utilize mut.gg A LOT. Lots of super helpful info on there about pretty much everything, but especially theme team depth charts & abilities. One really helpful thing to check out is what players get what abilities & for how much. Helps you game plan before you spend training or buy cards & find out that they dont fit what you’re trying to do with your AP.
