Vrabel, 49, was hired by the Patriots shortly after the end of the season. He takes over for Jerod Mayo, who led New England for one year. Celtics coach Joe Mazzulla, who’s in his third season as the top guy, spoke about what it was like having Vrabel around after inviting him to practice.

"Any time you can just get together with guys that are in the same arena as we are and support each other, I think that's important." The post Joe Mazzulla explains importance of ‘brotherhood’ among Boston coaches as Mike Vrabel attends Celtics practice appeared first on Boston.

And that gave Patriots first-year coach Mike Vrabel his first chance to see the team up close since assuming his new post. Coach Joe Mazzulla invited Vrabel to watch the Celtics’ session ahead of Sunday’s game against the Knicks.
