But Harrison quickly was proven wrong.
“Believe me, I wanted to hate this dude with a passion,” the retired linebacker said during Tuesday’s episode of FOX Sports 1’s “Undisputed.” “I get there and I’m like, ‘Dude, he’e the ultimate teammate.'”
So what exactly made Brady the “ultimate teammate?”
“I’m up there, and it was (during) the snowstorm they had. It was (a) crazy, crazy blizzard,” Harrison said. “Cats are like, ‘Man, we really got to go outside?’ Tom goes, ‘Hey, stop complaining. Let’s go.’ He takes off out there with just the little sleeves and all that for practice, like it was nothing.
“He’s the truth. I’m not going to lie.”
Harrison even told Brady he “wanted to hate” him, but Brady “just started laughing.”
While Steelers fans likely won’t like Harrison’s assessment of the 41-year-old quarterback, it certainly says a lot about Brady that even a former division rival couldn’t even bring himself to hate him.
