Not liking the headline prospect, already has a TJ surgery in his file, not coming back from it Harvey or even Strasburg style based on the numbers. For a stud like Giles on whom teams like KC build their bullpens, seems like they are outsmarting themselves here. Haven't read up on any of the other prospects, but this seems like not a great haul for a guy with many years of club control left.
The idea that we'll just find some bullpen arms later if we improve seems shortsighted. You need a couple studs, at least. Again, look at KC. Or on the flip side look at the Nationals last year. Phils' history in early-mid 2000s supports this -- that team would've been in the playoffs before 2007 if it had a decent 'pen, instead had washed up Jose Mesa, Turk Wendell types.
Doesn't seem like an adequate return.
