Years of team control remaining and age are huge factors in figuring out a player's worth.
Injury history is big, too.
How much success matters most of all.
These are 4 of the major factors, and I'm not sure anyone else matched even 3 of the four, closely with Crochet. This is a unique situation.
We got a very skilled pitcher with a proven, but very short, stint of success, and a history of injury.
The biggest plus about getting him vs 30-31 year old FA is his age. For that, we paid way less money but gave up 3 of our top 8 prospects. We obviously felt like he was good enough to be our #1-2 SP'er.
He becomes a FA at age 26 and turns 27 (June) that first year beyond our control. That is a great age to be entering the free market. Sure, how well he does over the next 2 years could place him in a range of an AAV of $5M to $45M and one year to 8-9 years, maybe even 10 years.
In some ways, it is a big stab in the dark, but I'd rather hitch my wagon to a 26 year old FA to 6 years than a 30-31 year old one to 6-8 years.
I could be terribly wrong, and we bash the trade and extension for years to come, but we got Price wrong, too, and just about nobody could have been viewed as a surer bet than he was, back then.
Roll the dice and get it done, ASAP!
