The former Rangers man was discussing Aston Villa's decision to look elsewhere than the Celtic manager.
Rodgers was one of the names linked with the Aston Villa vacancy - which has since been filled by Brentford's Dean Smith - despite a difficult start to his third season at Celtic Park.
The Bhoys have cruised to the Scottish Premiership title in each of the Ulsterman's previous two campaigns, but find themselves third in the standings, embroiled in a potential seven-way fight for the crown which includes their Old Firm rivals, Rangers.
And, according to McCoist, taking Rodgers out of the equation would have been a significant boost to Rangers' chances.
Discussing the 45-year-old's Villa Park links, McCoist told Wednesday's Alan Brazil Sports Breakfast: "I would have driven him down the M6 myself to take that job at Villa."
But when asked which of Celtic or Aston Villa is in fact the bigger club, the former Scotland international paused, before replying reluctantly: "Celtic".
Would the Celtic manager have been a good fit for Aston Villa?
