To celebrate his 44th birthday on Wednesday, Tennessee Titans head coach Mike Vrabel enjoyed joint training camp with the New England Patriots. Vrabel played eight seasons with the Patriots between 2001 and 2008. During that span, he won three Super Bowls and went to the Pro Bowl in 2007 after recording 12.5 sacks. It’s fair to say he enjoyed his time with the Patriots in the mid-2000s.

Vrabel is also having fun practicing against them. He gave quarterback Tom Brady a hard time for walking on the field, in which Brady responded, “Why don’t you pay attention to your own s***?”

Though the two sparred, it was obviously light-hearted, as Vrabel liked the time facing his former team:

“It was fun. It brought back a lot of memories, just to be able to sit out there and have him [Brady] make a play and he turns around and says, ‘Mikey, you know you better cover that. You guys need to do this. We had a lot of fun. We have a lot of respect for those guys and can learn a lot from them; how they practice and how they operate,” Vrabel said, via ProFootballTalk.

Vrabel isn’t quite a Patriots coaching disciple, as he got his pro start as a coach with the Houston Texans. But the Texans are, considering their head coach (Bill O’Brien) and defensive coordinator (Romeo Crennel), direct descendants of the Bill Belichick tree.

It’s clear Mike Vrabel remembers New England fondly, which tends to happen when you win three Super Bowls with a team.
