By now I'm sure you're all aware of the Erik Bedard trade. Personally I think we gave up way too much for him and fear that he's going to get injured and we'll see Adam Jones perennially in the all star game.
The acquisition that really intrigues me, however, is R.A Dickey. I know that most people don't get too excited about 33 year old pitcher who's missing his ulnar collateral ligament, but he seems to have honed his knuckleball. The Mariners picked him up in the rule 5 draft after posting a 13-6 record in AAA Nashville and bing named Pacific Coast League pitcher of the year. If he truly has dialed in his knuckler, he could really be a productive member of the Mariner's pitching staff.
