Plan for the draft and set a date/time for all the picks to be in. If that doesnt happen by your set schedule, have everyone that is interested submit 15 players to you (9 forwards, 4 D, 2 goalies....just an example) by a particular date/time. This means people will definitely have the same players on each team but I highly doubt you will see 2 teams with the exact same players because things are so diverse this season. This should guaranteee a playoff pool whether it is a 'draft' or a 'pick-em'
