NFL Hall of Fame inductee Richard Seymour belongs in this poll.
Yeah, it was quite difficult narrowing this down to the software maximum of ten choices.
Subtract one for the obligatory RLKAG and there's nine. I didn't want to waste a space on 'other' so I combined those two.
I wanted somebody from the sixties. Babe Parilli came to mind, but why two QBs? He could go on a Mt Rushmore of Pats QBs along with Grogan, Bledsoe and Brady, but this poll is more than that. Gino Cappelletti, Jim Nance and Houston Antwine were possibilities, but in the end I went with the OP's suggestion of Jim Colclough.
Choosing Hannah as a representative from the 70s was easy. I wanted at least a second player from that era too. There were plenty of good potential nominees: Grogan (again, no need for another QB), Steve Nelson, Stanley Morgan, Julius Adams, Raymond Clayborn, Sam Cunningham, Mack Herron, Russ Francis. In the end the choice was for Mike Haynes.
That makes four nominees, leaving six open spots. I wanted somebody from the 80s but that would leave just five from the Super Bowl era. It was difficult to not include Andre Tippett. I semi-justified that decade's omission based on Hannah playing through 1985.
The 90s gets left off this list because (a) a lot of those teams were devoid of talent, and (b) there was some carryover to the 2000s with Bruschi, McGinest and Law. Bruce Armstrong was close, but doesn't make the cut here. It was tough leaving Ben Coates off the final list.
Not including Seymour was difficult. Same goes for Vince Wilfork, Adam Vinatieri and Troy Brown. I considered Wes Welker because he was so incredibly productive, but in the end he was only a Patriot for six years, and played fewer than 100 games. Signing with Denver removed any doubt.
Based on the results thus far perhaps McGinest (and/or Law, Bruschi) should have been left off in favor of Sey, Vince, etc. The poll would have been illegitimate without BB, TB12 and Gronk, so there wasn't a whole lot of room to maneuver.
@Pape - I should have consulted with you before adding the poll, hope you don't mind.
