Could I have your recommendation please

Im getting all the Nfl teams from Miggle.Mostly so if someone wants to play a game they can pick thier team.Question is what numbers do I put on them?The players are the fab 5 from Miggle.The decals will be the one miggle sells for around a $1.50 the peel off ones.As far as a rosters go Im not sure to do a modern team,a historic team or an all time team.Thats what Id like to hear from and your recommendation on which numbers or team to go with.Thanks
