Unless I'm not seeing something totally obvious, WHY ARE YOU EVEN WORRIED ABOUT THIS ??
As for BE A GM - I think that should be rebranded (At least offline) as BE AN OWNER & modeled like Madden CFM where you play as THE OWNER of a team rather than as a player
I get why EA won't allow/support BE AN OWNER be an online mode however (Heard there was too much in-fighting going on. Not cool
)
As for your BE A PRO issues - I'd say CHECK YOUR SLIDERS 1!!
