[3] Ohl attended Edwardsville High School, where he averaged 19.6 points per game in his senior year, 1953–1954, and his team finished fourth in the Illinois state basketball tournament.

[1] He averaged 6.7 points per game as a sophomore, 15.6 as a junior, and a team-high 19.6 as a senior in 1957, being chosen team most valuable player as well.

[1] In his final college season, Ohl began to pique the interest of several NBA teams in advance of the 1958 draft.

[1] As Ohl told The Edwardsville (Ill.) Intelligencer in a 2008 interview, "'It may have been a mistake, but I didn't end up playing in the NBA until two years after I got drafted.

I started working for Caterpillar and they had a team in the Industrial League, which might be comparable to a farm club of the NBA.

[1][4] He was scouted by Detroit Pistons coach Dick McGuire, who acquired his rights from the Warriors, they made an offer that Ohl couldn't turn down.

[9] Ohl twice scored a career high of 43 points in a single game, first on January 23, 1963, in a 123–119 defeat against the Los Angeles Lakers and again on December 25, 1966, in a 129–127 loss to his former team, the Pistons.

[10] Shortly after the 1963–64 campaign, Ohl was involved in one of the first so-called megatrades, this one an eight-player blockbuster between the Pistons and Bullets.

"[4] In the 1964–65 campaign, Ohl, backcourt sidekick Kevin Loughery and the front line of Howell, Walt Bellamy and Gus Johnson carried the Bullets to the first playoff series victory in franchise history, a four-game upset of the St. Louis Hawks in the Western Division semifinals.

In the Western Division finals, he and Los Angeles Lakers star guard Jerry West were involved in one of the more memorable shootouts in league postseason history.

[11][4] "(Lakers co-star Elgin) Baylor wasn't playing -- he was hurt," Ohl recalled.

(Fred) Schaus, the coach, just put him on the side of the floor, gave him the ball and let him work it in until he got a shot, because like I said, Baylor wasn't playing.
