I agree with that 'billiards and snooker greats have no place in this thread.' I do think that tournament victories cannot be the judge of who the greatest all-around player is/was. The game of pool has a history of tournaments not paying a professional wage that the best players made their money playing in money games instead of tournaments.
Shorty's achievements of playing at all pool games at a very high level should be judged by his success at winning money and not by how many tournaments he won. He simply didn't enter tournaments that he could have won because the return on investment was not worth it. In those days success in tournament play could harm an ability to make money games.
I am not saying that Shorty definitely was the best all-around player ever...I am just saying that he should be considered an important part of the discussion.
In spite of Shorty's lack of tournament credentials his skills were recognized enough to be voted into the BCA Hall of Fame. Here is Shorty's bio on the BCA website:
"Larry Johnson studied the techniques and shots of Boston's best. By age 20, he could beat the players he studied. Unfortunately, his skill prospered during lean times for pool (the 40's and 50's), and so, the record books don't fully credit the skills of many of the players of that era. But, Boston Shorty was simply one of the very best. Johnson was not only a top 9-Baller, but among the cream of the crop at Rotation, 1-Pocket, Straight Pool, 3-Cushion Billiards, 8-Ball, Cribbage, Cowboy and more. During the famed Johnson City and Las Vegas events of the early 1960's, Johnson captured World All-Around Champion in the last staging of both events, and later collected many other titles. Johnson mastered all games early in his career and played at that speed for four decades."
