Offensive Chems Help???

I havent spent any training on changing my offensive chems from just the free balanced O. I know on D having the DBs and SSs with LD and then any coverage LB too. With all your DL and pass rushing LB with PR. Last year you wanted GD for the QB and WR and then I couldnt remember which one for the OL.

So can anyone help me on which is the go to chems for the O this year? Doing this for my Titans theme team which is just sad.
