Tecmo Super Bowl

[snesmaster]

Hi, I have decided to map out this game.  However I don't know much about football, so if anyone does, can you assist me with a proper starting position to place the sprites of the players in.

Here is what I have at the moment:

Questions:
Are they in the proper positions?
Are there other players that should be added to the field, and if so where?
