No, partnership because Jim Irsay gets to draft Peyton Manning and doesn't have to negotiate for him against every other team in the NFL when he becomes eligible for the league.
Hmm, so one partner usually drafts the other partner?
This line of thinking is fudged up beyond comprehension.
The argument has always been players don't get hired by individual teams; they get hired by the NFL. The players' choice is whether they want to play in the NFL, UFL, XFL, Arena League, or whatever.
