Yes , it's very possible that the Colts , Houston ,TB , SF and Chicago could all finish with 4 wins. No coin flips unless Strength of schedule ends up tied. Chicago , Houston and the Colts each have a winnable game.
Colts win strength of schedule tie breaker with all these teams. So they clinch 3rd pick with 1 loss. Now when you go to the second round , the order reverses. So the team that picked 7th i the 1st round would pick 3rd in the 2nd round and the team that picked 3rd would pick 7th. Pretty sure it just reverses order.
