You're right, I shouldn't have called it an "issue." That's my own subjective reality, since everyone I've ever known who was told to lose a few pounds eventually had it turn into an issue when they put them back on.
But Raffy's a young man and pro athlete, so should have proper guidance, including trainers and nutritionists, to keep him fit at least through the next decade of a rich contract.
The injuries that happen to all these guys are typical, but how they adapt is what separates them as they mature. For example, if you rely on speed, pick your spots as a baserunner, because every slide is another body-slam into the earth. Or if you have a sore elbow or hammy, don't try to freaking crush every pitch...
