He's become a filthy rich man no matter what you compare it to. $63 million/$85 million is still $63/$85 million dollars and that isn't even considering the millions he's made on merchandise deals and other non-football streams of revenue. The value of those dollars do not become less because another WR is making more. I understand Julio's line of thinking. But his line of thinking is being done in a vacuum. If we want to talk about "industry standards" or "common practices". Then anyone can easily point to the fact that it is not common for NFL teams to re-do contracts with this many years left on it and there are very sound business reasons behind that practice. Is Julio more valuable than Landry? Yep. But this is more of a case of what Landry's agent got for Landry due to dealing with a team who has historically made atrocious football moves across the board. Than a case of the Falcons "doing Julio wrong".
Using your accountant example I can tell you exactly what would happen because it's been a real life one for me over the course of my accounting career. If I were to walk into by boss' office and express my thoughts on my pay he would then turn to me and say- "We will revisit this when we do yearly performance reviews." Because that is the time when employers (or the one's I've worked for) have designated as the time to discuss merit raises and employee terms/contracts. Not halfway through the year. The same goes with Julio. His employer has appointed a time in which they are willing to discuss new contracts and basically by Julio signing his contract he also agreed to those terms. Now the employer has at their discretion to opt to begin these talks a year early. But that is the employer's option and isn't something they are contractually obligated to do.
Here's the thing though - there's not just one way to negotiate. IRT the example you gave when your employer stated they would only discuss salary increases at a yearly review; I've had the exact opposite happen to me recently. I talked to my supervisor about a raise to bring me in line with industry standard and they gave me a generous raise - and then 2 months later was my merit/anniversary raise and I got my scheduled merit raise also. So, all that to say there's not just one way to negotiate. Some players report to camp while negotiating something like this and some don't. I do agree that having 3 years left on the contract isn't a good look. IMO there's substance to both sides of the argument. If he misses an actual game over this then I'll jump on the "I've lost respect for Julio bandwagon" but until then it's just negotiating..
