I propose that prior to every season commish team delegates 2 offensive and 2 defensive franchise players on every team that are untradeable. Star players, or star prospects, franchise cornerstone type players etc.
For example:
Houston Texans
1. JJ Watt, Star player
2. J Clowney , Star Prospect, top 5 pick
1. Deandre Hopkins , Star Player
2. Lamar Miller, Star player
