There is and always has been one glaring con to any Noah Syndergaard deal. The guy just can’t stay healthy. He’s only pitched a full 30 games once in his career.
Add to that the fact that he is having the worst season of his career and the idea of giving up very much for him would make even the most bullish GM hesitate. Not only is Thor’s ERA (4.68) nearly a run and a half higher than his previous career-worst, but his strikeout rate is also down, currently less than a strikeout per inning for the first time in his career.
Thor is still young and a change of scenery would certainly help his production (and maybe even his health as it seems none of the Mets can ever stay healthy) but would the Rockies gamble on having that change of scenery at a mile above sea level?
Like most of the pitchers on the market, Thor would be an improvement to the Rockies’ staff, but would he be worth what they’d have to give up to get him? With their offense, the Rockies can probably get away with league-average pitching (their pitching is currently well below average so this would be a huge upgrade), but do they want to pay the price for elite pitching to get league average pitching in return?
Whether they like it or not, they might have to. If they do decide to make a big splash, Thor has the stuff to pitch at Coors Field as long as he can stay healthy and due to his contract, he would be a part of the rotation for years to come.
