Sorry, but there a lot of guys on that list that I would rate over Scott Frost. In fact, most of them! Bugs, Taylor, Ronnie, Efren, Rags, Cookie, Marvin. C'MON, these guys were great players! These are not shortstops here. Kelly, Shorty, Cooney, Jersey Red, Cornbread! PLEASE. If Scott Frost got a steady diet of these players, he would have to find a new job.
I'd like to see Grady chime in here since he played so many of the above guys, and held his own. And he's seen Scott play. In their prime Sigel and Mizerak would have chewed him up too. Probably Hopkins and maybe Rempe, Varner and Fusco as well. Scott has a huge offense but the guys I listed were just better pool players.
P.S. Ask Scott how he came out with a 60+ Ervolino in Vegas about ten years ago. The best One Pocket players of this current generation IMO are Shannon and Gabe. Joyner was a better player too before his shoulder went out.
