Teams upgrade their weaknesses out of convenience, not necessity. It?s usually just easier to replace your worst player with a mediocre one than swap out your solid player for a great one. But the Blue Jays were in a bit of a unique position, with a window to win that extends through 2016 but maybe not beyond that ? Jose Bautista and Edwin Encarnacion are both free agents after next year, and while Russell Martin was a good addition, he?s not going to be an elite catcher forever ? so Alex Anthopolous was wary to use his farm system to make a move that only helped this year?s roster without also upgrading next year?s Blue Jays team as well.
And while there are a lot of pitchers available right now, most of them are headed for free agency this winter, with Cole Hamels and Aroldis Chapman being the notable excpetions; the Blue Jays are on Hamels no-trade list and the price for Chapman is reportedly quite high, especially for a guy who throws just 15-20 pitches per appearance. So if Anthoplous found every team he called asking about his best young prospects ? and that was reportedly the case when they tried to engage on Johnny Cueto ? then upgrading at shortstop with a player who won?t leave this winter might very well be preferable.

Which is why the Jays also had to part with some of their young talent in order to get this deal done. Because the deal isn?t known in its entirety as I write this, I?m going to hold off on declaring whether the return justifies the price, but we do know that Miguel Castro and Jeff Hoffman are part of the return going back to Colorado, with one other additional piece apparently in the deal as well.
Kiley McDaniel rated Hoffman as a 55 FV, placing him #67 on his pre-season Top 200, and confirmed that he?d keep the same grade on him after seeing him a few weeks ago. As a guy working his way back from Tommy John surgery, he?s certainly a high-risk prospect, but one with significant value given his upside. Castro, rated a 45+ FV on the same list, is also a pretty high-risk gamble, given that he?s basically all arm strength at this point, showing no real ability to get either big leaguers or Triple-A hitters out this year. The Blue Jays rushed him up the ladder, and perhaps the Rockies can get him back on track with a more cautious development plan, but he?s going to need more than just a poorly commanded fastball to turn into a good pitcher.
In terms of prospect value, these two look fairly similar to the two primary pieces the Reds got in exchange for Cueto. If the third prospect in the deal is the least valuable of the trio, then it may very well be that the Blue Jays paid less to get Tulowitzki than the Royals paid to get their rent-an-ace. Perhaps we?ll find out that the third prospect is actually another valuable piece, but as it stands right now, it seems like this may very well have been a better use of the team?s prospect currency than swapping it for a few months of a starting pitcher.
