What would you look for in a contract, trading clauses, years, little perks?
Let me be more specific, say you're 28/29 at your peak, you've bolstered a 4.5 WAR each year since your rookie season, all with the same team. (I'll let you decide if you're a hitter or pitcher, which is also why I didn't go in depth with other stats.) you also don't have an injury history and no attitude problem playing whatever position you decide.
This thread seems silly because there are so many variables that go into it however, your imagination will also say a lot about your character. Will you try to have a contract that breaks bank? Something long? Would you want to play for the same team (let's say your home team is the team you play for.) would you want a no trade clause?
The reason I make this thread is because it'd be interesting to see what people would say they'd demand on the open market although who really knows how those negotiations would go, your worth is determined entirely by yourself.
Also, some comparable people would be Jayson Werth, Homer Bailey, Madison Bumgarner, Ian Desmond, etc.
