One of Paul Tagliabue's final achievements as NFL commissioner didn't sit well with his bosses, the owners.
It happened during a winter day in 2006 at an airport hotel in Dallas. The league's salary cap, first established in 1994, was set to expire. Frustrated owners kept debating the merits and costs of continuing the system. Meanwhile, NFLPA boss Gene Upshaw was on a flight to Hawaii for a board meeting with his union. The potential for labor disharmony was very real.
