There are only three dates that produced two Hall of Famers with over 1,000 career points.
Darryl Sittler 1,121pts, Peter Stastny 1,239pts. Also Bun Cook, all three Hall of Famers.
Mike Gartner 1,335pts, Denis Potvin 1,052pts. Also Eric Staal.
Johnny Bucyk 1,369pts & Bernie Federko 1,130pts
A few other dates that could contend for the best hockey birthdate:
Rod Gilbert 1,021pts, Steve Shutt 817pts both Hall of Famers. Also Jarome Iginla 1,106pts and a future Hall member.
Alex Delvecchio 1,281pts, Dave Taylor 1,069pts & Rick Middleton 988pts. Only Delvecchio in the Hall.
Terry Sawchuk, Harry Howell, Ray Bourque. All Hall of Famers.
Gordie Howe, Pavel Bure & Bob Pulford. All Hall members.
Mario Lemieux and Patrick Roy. Tough to beat one of the top five skaters and goaltenders of all-time.
In the end, we may have to go with January 22 as the greatest hockey birthdate mainly due to the fact that is the only one with four Hall of Famers born.
