 he can only get to 99 with a Theme team?

99 OVR

In for an answer.

I have madden passing x2 rushing x1 tier 3 sprinter and maxed wc and he’s sitting at 98.  Thought t3 Sprinter might get him to 99, but nope

I have Falcons Passing Chem almost maxed out. My Vick is absurd.

I’m assuming max sprinter/coach madden/scheme chem

mine is a 98 with t1 sprinter and t1 madden passing so I’m assuming he will be a 99 with t3 sprinter and t2 madden passing

West coast n max sprinter he goes to 98

Got Madden x2 passing & Max Go Deep & he is still sitting at 97 after I upgraded him today... how do I boost his ovr? Am I using the wrong chems?? Same With Gonzalez I can't figure out how to upgrade him to 98 or 99 ovr I've been stuck on 97 ovr with Tony Gonzalez as well :(  

Yet I've seen Gonzo & Moss at 99 ovr in squads & h2h countless times... how are they doing this?? Is it Sprinter or what?? Thx for those who can help...
