I'm in the disapprove camp, though admittedly the needle has swung from strongly approve to disapprove over the past 3 seasons. The brilliant trade to unload wells was the high water mark for me. Then it started to go backwards 24 hours later when he traded Napoli for a bad closer. Right there it started to become apparantthat his player valuation system was flawed.
He did well to exploit the comp picks before mlb closed that loophole. But then he traded for overpriced talent and gave away way too much for a f***ing 37 year knuckleballer because he'd won a Cy Young....and the Florida trade was further proof that his valuations were suspect. He completely ignored the free agent market when it could help the club. Starting pitching has been the biggest need for 3 years and there's been nothing done about it except trying to catch lightning in a bottle year after year for rotations spots 4 through 8, when he should have been focusing on improving spots 1 through 3.
Too many spots in the past 3 years have gone to replacement level or lower players when they're supposedly trying to contend.
From year 3 on, it's been basically knowing what needs to be done, but never getting it done. Theres been good moves since then, Ala Donaldosn, Martin and Travis. But complete failure in addressing the teams pitching needs is once again the anchor weighing down the team.
For me, if he doesn't swing something before deadline that improves the teams pitching in a meaningful way, it's probably time to cut ties.
