Hannah joined the Patriots in 1973 as the 4th overall pick in the first round of the
1973 NFL draft. He played his entire professional career in New England. While considered somewhat short by NFL standards, Hannah made up for this with great speed and quickness as well as powerful legs. Hannah excelled as a pass protector, as a run blocker, and as the pulling guard on sweeps. Hannah's commitment to football was very high and he expected the same from each of his teammates, sometimes becoming quite angry if he felt they were not complying. Hannah started the first 13 games of his rookie season of 1973 until a freak leg injury forced him to miss the final game of the year. Along with tackle
Leon Gray, the two formed what was generally considered the best guard/tackle tandem in the NFL during the mid to late 1970s. Gray and Hannah also combined with tight end
Russ Francis to form one of the strongest left-side trios in the league. Hannah anchored the 1978 offensive line that set an NFL record with 3,165 rushing yards. The record breaking rushing attack of New England did not have a single 1,000 rusher, but did have four players run for more than 500 yards including quarterback
Steve Grogan. The team rushing record would eventually be broken by the
Baltimore Ravens some four decades later, but the 1978 Patriots also set a
league record with 181 rushing first-downs, which still stands as of 2022. Hannah missed only five games out of a possible 191 because of injuries during his career. He also missed the first three games of the
1977 season when he and Gray held out because of contract disputes. In the
1985 season Hannah helped guide the team to its first
AFC title and Super Bowl appearance. Hannah retired from the NFL after playing in
Super Bowl XX. Hannah was named to ten consecutive
All-Pro teams (1976–1985), and was named All-
AFC 11 times (1974, 1976–1985). He was also selected to play in 9
Pro Bowls. He was voted the
Seagram's Seven Crowns of Sports Offensive Lineman of the Year in 1978 and 1980 and won the NFLPA/
Coca-Cola Offensive Lineman of the Year Award (voted on by NFL players) three times in four years (1978–1979, 1981). Hannah was also the winner of the
Mack Truck Award for offensive line play five consecutive times (1977–81). He is also one of the few players to have been named to two different
NFL All-Decade Teams (for the
1970s and
1980s). In 1994, he was then selected to the
NFL 75th Anniversary All-Time Team as the #1 guard on the team. In 2019, Hannah was then selected to the
NFL 100th Anniversary All-Time Team. In 1991, he became the first Patriots player inducted into the
Pro Football Hall of Fame. In 1999, he was ranked number 20 on
The Sporting News' list of the 100 Greatest Football Players, the highest-ranking Patriot, the highest-ranking guard, and the second-ranked
offensive lineman behind
Anthony Muñoz. In 1991, he became the first player to be inducted into the
New England Patriots Hall of Fame. ==Coaching career==
