Folks are assuming he was entirely welcomed to go and not that he wanted a change of scenery himself. He may not want to play in this scheme, and / or see himself in a better spot next to Chubb. He may have just wanted out of the PNW and prefer the sunshine and prospect of playing in a group where he'll be a part of what looks to be a formidable team, rather than again being expected to be a critical piece in a group (on D) that's been a dumpster fire since he's been here.
Brooks is without a doubt a good player who's production and performance has been dinged by the defense he played in and those who led it. He gets dinged for ONLY being a tackling machine when that's pretty much all that Bobby's been for the last 3 years.
As to Brooks v Queen. Even NFL talking heads were giving us the better end of that deal... until Smith and MM got to Baltimore. I watched Queen in Baltimore since he's been there and save for the last 22 games, he was definitely NOT the better of the two players. He was pretty much considered a JAG and nothing special, flashing every once in a while... until the Smith trade.
If he's healthy, I expect him to do very well in Miami.
Pretty bummed about him and Parkinson leaving.
