It probably is rigged because voting is "unlimited." Which means EA can use a BOT to choose who they want to be on the cover.
But I highly recommend you guys check this video! Lets find out if its rigged.
only problem with that video, is his rant about kessel (cover of a nhl 2k series).
i could be wrong, but crosby is also a cover boy for the 2k series and or just recently on the cover of the ea cover.
and a lot of the problem with not having certain players involved in these votes, is the rights to the players. since being a part of the EA games is that EA essentially becomes a sponsor for that said player.
