According to Lance Zierlein of Sports Talk 790 in Houston, Percy Harvin was a head case in Seattle. He was in several fights with teammates including both Russell Wilson and Golden Tate.
@LanceZierlein: Heard “anger management” had quite a bit to do w/ Harvin’s departure in Seattle. (1/2)
@LanceZierlein: History of confrontations w/ teammates contd in SEA according to my guy including punching G Tate during SB week & near fight w/ #3 in ‘14
@LanceZierlein: I was told “Harvin’s anger issues are just too much to deal with and he could single handedly bring down team chemistry”. Wow. Unreal.
@LanceZierlein: I was told “Go find a team picture from Super Bowl and you can still see part of the black eye Tate got from Harvin”
We at NFL Draft Diamonds went out and found a picture of Tate for you.
