Dolphin fans are way overboard with Ireland hate. Yes, he isn't a good GM, but he isn't incapable of evaluating talent entirely. He does have value to an NFL club in some capacity, just not as the guy in charge. He is a decent scout for some positions, notably DL. His issues were personality-based and arrogance.
Dropped us to the depths? We won ONE game before the Trifecta got here. Ireland was able to acquire enough talent to make us consistently mediocre again. I hate defending the guy, but the level of hyperbole around him from Dolphin fans is a bit too much to bear.
As sad as it is, Ireland was probably the best GM the Dolphins have had in the past 15 years from a scouting perspective. His first round picks were never abject failures like Ted Ginn , Jason Allen, and Jamar Fletcher. They were solid, productive players by and large. His kryptonite was the 2nd and 3rd rounds.
