Cecil Frank Isbell (July 11, 1915 – June 23, 1985) was an American football quarterback and coach.

[1][2] Isbell was the head coach of the Baltimore Colts of the All-America Football Conference from 1947 to 1949, resigning after four winless games.

When Lambeau resigned late in the 1951 season, Isbell was the interim head coach for the final two games, which they split.

In the summer of 1938, he led the College All-Stars to victory over the defending NFL champion Washington Redskins at Soldier Field in Chicago.

[4] Isbell was selected in the first round of the 1938 NFL draft by the Green Bay Packers, the seventh overall pick.

Isbell was a very accurate passer and a good runner and he led the Packers in rushing and passing in his rookie year.

This time the game was played in Milwaukee and Green Bay crushed the Giants, 27–0, with Isbell throwing a 27-yard touchdown pass.

Isbell became a more accomplished passer during this time, connecting regularly with Don Hutson in record-setting frequency.

[6] The Packers finished the season tied with Chicago, but lost to the Bears in a divisional tiebreaker playoff, 33–14.

The Professional Football Researchers Association named Isbell to the PRFA Hall of Very Good Class of 2008.
