I'm about to start breaking away from this BND only lineup. This is where I'm at right now plus the LTD Manziel I just pulled being my first non BND. I have 3 million coins as well. Also have my free BND 99 waiting to be opened after I see what drops this weekend. I use the 99 Zach Allen as my 2nd rush DT. He sucks at DE.

I'm also interested to see if you recommend different backups to boost special chess from promos etc... right now I use some combine, TT balanced, AKA and Denver
