Why do these pro athletes hold out for new contracts when they may be in the middle of their current contract? They signed it, just be a man of your word and live out the details you agreed to at that point.
With Julio Jones, I'm not sure how you could expect to sign a 6-year contract and still be the highest paid receiver in the NFL even halfway through it. You want the longterm stability but only if it's on a sliding scale. Missing mandatory camps could start some resentment soon enough.
When he signed his contract, he became the 2nd highest paid wide receiver at that time. If he wanted to get a new contract at this time, he shouldn’t have signed a longer contract back in 2015. I’m sure if he sucked now, he wouldn’t be returning any money.
