I guess I'm wondering on your basis for that? The trend curves aren't perfect and not everyone will decline. Tulo might well be a productive offensive and defensive player for the rest of his contract, but the aging curves do indicate that into their 30s declining play is just part of the expectation for most players. I think, in the case of Tulo, it might have extra weight given the fragile nature of his last few seasons. Maybe those were just flukes, but to me they are heavy indicators of risk. Not enough for me to write off trading for him, but serious enough to heavily weigh on the decision.
