Agreed - what about the flip side and having Riley (or whomever) beat us up for 6 or 7 years? You'd think the Marlins would enjoy that. Since they're rebuilding they shouldn't care who they trade with as long as they get the best return
The Marlins, and Jeter, are incapable of thinking like this. They're extremely narrow-minded, short sighted, stubborn, and focused on what the fans would think in the short term with one of their players going to rival and helping beat them. However, they lose sight on the fact that 1) they're not that good anyways and would have likely lost to said team and more importantly 2) the main objective is to maximize your return to improve your own ball club. Forget about the other ball club you're trading with, focus on yourself. Is this making you better and the best offer you are receiving? If the answer is yes, then make the trade.
They're likely going to hold on to JTR, continue to lose, flouder at the basement of the NLE, play this whole trading game tease next off-season, get even less of an offer, still not trade him, and then he's going to walk. And what's going to be funny is if JTR signs with us when he's a free agent, beats the Marlins, and they have nothing to show for it.
Jeter is a joke and way in over his head. He has no business running that team and knows very little about what makes a great owner and how to run a franchise.
He was a great ballplayer, but he's anything short of a lackluster owner. But he's letting his ego get in the way of himself.
