I would honestly probably advise against using SFL if you never have. It really is that game changing that for me at least once you use it you cant go without it. Lol which im not being sarcastic because it comes with limitations like only a small handful of qbs you can use (an otherwise great free season Vick isnt one of them) AND basically speaks for ALL of your offensive AP. Especially pairing either gunslinger and/or HRM depending on the qb.
My first experience with it was Aikman, then Marino, then went to free vick to use coins elsewhere, couldnt last that way but a day or two. Had to go buy Mahomes to get it back. I kinda wish EA (even with how OP offense is and useless D is) would bump up the AP a bit. Maybe even just go up one each. Make offense 8 and defense 10.
