This might be a rare 3 team trade in which everyone makes out well.
Phillies upgraded from Lee to Halliday (yes that is an upgrade, dominating the al east is more impressive than the al central or nl east). The reported price is high, Taylor is a very good prospect, but if Halliday signs a 3-60 contract it is worth it. On the open market I would suspect Halliday would approach 6 years 150 million. Not having the 20+ million risk of years 4-6 is significant.
The Mariners got Lee for a bunch of prospects. This trade is about 50 times better than the Bedard one. For starters none of their prospects is close to as good as Adam Jones was and Lee is much less of an injury risk. Additionally Lee may very well make the difference between a post season spot and not (and in the postseason you have to like that rotation), while the 2008 team wasn’t any good with or without Bedard. It looks like the Mariners are making a run before King Felix hits free agency. They just need some offense. A great trade for Lee too, he will love pitching behind that defense.
The Blue Jays showed out it is done getting a much better package than Minn or Cle did from their aces. Give some credit for J.P. too holding on to Halliday when everyone said he needed to trade him. I don’t think they get this kind of package in season. A very nice head start to rebuilding, though their system is still pretty barren.
