Couldn't have said it better myself. The main blinders with people who are prospect/young player friendly is that they far overvalue their worth. KC gave up way more to get Shields and Davis and we're already seeing a taste of what Myers can do right now.
I recall people had no issue with Snider giving handshakes in the dugout when everyone assumed he was being traded for Garza. Then it turned out to be Lincoln and there's been constant crying about how the Jays gave up on him. People didn't have a problem with the idea of giving up on Snider, they had a problem with AA not waving a magic wand and getting a king's ransom with horse manure. The market dictated that all he was worth was Lincoln. Nothing more. And he continues to prove that point while with the Pirates.
If you look at the Dickey trade in the context of the Shields trade or other veteran-for-prospect type of trades within the past decade like Josh Beckett or Bartolo Colon, the Jays did just fine. The only reference I see the Dickey trade being specifically referred to as bad is how they missed out on Latos with a similar package. First, we'll never know the full story on that one so much of it is hearsay, and second if this was their runner-up trade, getting the previous year's NL Cy Young is a pretty good consolation prize. Latos is a free agent in 2016 while Dickey is signed to a relatively team friendly contract through then. There's a good chance that the Jays get Dickey for longer than the Reds will have Latos, unless they sign him to some expensive long term contract. The biggest negative factor is age, but with a knuckleballer that becomes a huge wildcard where age might not be a factor at all.
I think the prospect love-in by the board is a product of a couple of big time posters who are in love with the way TB does things and that spreads among the younger crowd who are too easily influenced by what they read. You don't just turn every pitching prospect you have into David Price, and if you do, it's a mix between great luck and very good player development.
If we examine that TB "success" more closely, 2013 is essentially their version of the 1992 Blue Jays as they are 21 years younger. And the 2013 Rays are nowhere near the talent of the 1992 Blue Jays, nor anywhere near the success. What the Jays did in the 1980's pisses all over what the Rays have done so far (even with the one WS appearance) since 2008. What the Rays are is a team that has done pretty well for their small budget. For some reason people care more about that than winning at all costs (the Yankees model) as if they are in the accounting department for Rogers.
