I haven't been on this site very long, but if it's like "the other one", my guess is that if Espi becomes the next Pedro, 80% of the board will say, "I told you we overpaid". Maybe 50% will say they were against it at the time.
For years, I've heard the complaints that our system never produces any aces. We finally get a pitcher who might be the highest ranked 18 year old starter in a very very long time (I'm still waiting for some research on this point), and we buckle under the pressure of a need for a number 3-4 type starter on a team that finished last in 3 of 4 years prior.
Trading Iggy for Peavy, or Stephen Fife for Erik Bedard is one things, but trading a top 12-15 pitching prospect like Espi, in my opinion, was a huge gamble and a huge mistake. Even if Pom pitches like a number 2 for the remaining two years on his deal, I think it was a massive overpay.
