Backup players suggestion:
Why can't a single player backup more than 1 position? I feel like we should be able to have a 'swing end' or something to similar effect. Especially if it's someone like a DE3 when I'm running a 4-3 that could slide in and be the backup DT with a pass bias and a backup DE with a run bias.
That's a pretty standard use for that size/type of player.
