Its not holding out when you aren't under contract. Emmitt was merely going through contract negotiations and wouldn't have been able to report to training camp if he wanted too. He couldn't have done it because he had no contract. Why is that so hard to understand?
Zeke held out with 2 years left on his contract, demanding more money like a greedy sum beach.
At least Emmitt had just come off a super bowl championship, unlike this poor excuse for a RB that you are somehow trying to defend. It's a stupid excuse to say 'Emmitt held out too' when trying to defend Zeke doing far worse.
