On the latest episode of The Gridiron and Beyond, Bob Socci sits down with Dave Birkett of the Detroit Free Press (@davebirkett) and Pro Football Hall of Fame selection committee.  

We discuss the start of NFL free agency, including the Lions' signing of several ex-Patriots -- most notably, Trey Flowers -- and why it was critical for GM Bob Quinn and head coach Matt Patricia -- themselves formerly in New England -- to make a big splash this offseason.

Plus, who Brian Flores has tabbed to be his veteran voice of reason as a first-time head coach in Miami...

How Kyle Van Noy took advantage of his new surroundings in New England after being drafted by Detroit...

What Bill Belichick did to moonlight during his two seasons as a young assistant with the Lions...

And whether Rob Gronkowski deserves to be a first-ballot Hall of Famer.
