Me too actually. I have spend for my guards 2.8M(b4 the change of the economy, now worth at very least 1M+) and for the 2nd 4.2M. They both have pitiful on IS/ID, but the 1st was MVP in CBBA last season, key factor for 1 championship and 1 cup. I really dont see the need to have those big men skills. For the rebounding/interior D i have my big men. Yes every skill that a player have is usefull, but u cant have it all, and for sure doesnt worth to over pay for those.
What i think that is a must for every player: Able to shoot, play D, and pass, everything else is welcomed, but not essential. Thats my opinion
