Bruce Shatel always ribbed Sean Gleeson about his body language.
From 2008-11, Gleeson assisted Shatel with the baseball team at Delbarton School, a private, all-male high school in Morristown, New Jersey. It was one of numerous tasks for Gleeson in his first job out of college; he taught English and algebra and coached baseball, football and bowling.
In baseball, he was Delbarton’s first-base coach. And his energetic, excitable approach to coaching shone through — sometimes, almost too much.
“Any time we’d put a squeeze on, or a hit-and-run, something where there’s high risk, high-reward, Sean’s body language ... He’s already 6-foot-5 or 6-foot-6, he’s a tall drink of water. He would get on his tippy-toes and get all excited,” Shatel said. “I said, ‘Hey, can you calm down over in that first-base box? You’re going to tip the squeeze!’”
Merely eight years after his last season as an assistant baseball coach at Delbarton, Gleeson is Oklahoma State’s new offensive coordinator. His rise in the coaching profession — from high school, to NCAA Division III to FCS to the Big 12 — in less than a decade, and at 34 years old, was only possible because of the qualities Shatel saw in him over those four years together. Shatel called Gleeson a high-energy go-getter who was bright and capable but “willing to pay his dues.”
Funny thing is we've been using almost exactly the same criteria and using it for analysis purposes in defining a success play as Gleeson. His success rates based on that video are definitely higher than OSU 2018 was.
