I think u should get the chance in franchise mode to send some of your younger, not so talented players off to nfl europa at the end of the season (say perhaps 1 player to each team). You should then have the option 2 play out the NFL Europa season personally, chose a team which one of ur players is on and play the Europa season. That way they can progress and become more useful to you in the regular NFL season. However whether you want to play the Europa season should be optional. Also the players eligible should be restricted to 3-year pros or players under a certain rating e.g.78. That way you can have more 6th rounders in the franchise mode for other teams rather than everyone having solely first rounders which can get kinda boring.
