I think the game would've been cool if all abilities were entirely hidden.
It would've been cool to have an "advantage" on your opponents because you have a better idea and understanding of the strengths of the players that you select. (from watching these studs in their hey-day or using resources on the web to find out more about the legends/players in the game.)
I think this would've did a good job at adding to the strategic depth, learning curve, and replay value of the game.
Plus with every game you play you would learn something new about your players.
