Ok, but that’s a huge factor.
Trade value is a meaningless concept; it’s not like a price tag in a store. Websites like BTV calculate it based on WAR and salary, both current and projected. But that’s a lot of guesswork and future voodoo involved that may or may not come true.
While most teases probably use similar systems, at the end of the day, only two real world factors establish the value. 1) How much Team A wants to trade the player and 2)how badly Team B wants to acquire him. If Team A wants to dump him for salary reasons or attitude problems or he whines when asked to play first base, then Team B can probably get him for less. But if Team B wants to acquire a player more than Team A wants to deal him (especially if they need to outbid Team C), then the price goes up.
There has been far more buzz about Duran than Bubic. But Bubic is a pitcher, which is always in high demand. But I don’t think that alone puts him so far ahead of Duran and his extra years
