1. I pay for what happened which likely suggest me what will happen when a guy still has enough gas in his tank. Not otherwise. You do not pay for a track record of mediocre numbers, hoping excellence just because he is young. Look at Papelbon, pretty similar case at the time (excellence + durability) and still like the good wines, posting ridiculous ERAs and saving bunches of games AND Still Durable as I projected.
2. I just showed you his numbers, why do you refuse to accept that he is a True No.1 and still relatively young and at his prime. You think he is not a bargain? Fine!, Please name 5 pitchers who are making less money with his track record AND durability at 30 or less. I'll wait.
3. A DR% below 2 digits doesn't justify high AVV for mid-term contracts for mediocre pitchers, sorry, mid-rotation guys like Porcello unless he improves, say at 3-4 WAR range (No. 2 type). That's the drum I've been beating, nothing more, nothing less, reason why I offered a public bet (for fun). Engineering Economics apply regardless the industry when cash flow is on the table. This is why I say you do not understand the time value of money; you just don't. I do not mean it as an insult either.
