I won’t deny that he had potential, but he was hardly the sure thing with Winnipeg that people seem to remember with 20/20 hindsight.
His 1990 Grey Cup performance was one TD pass in garbage time with the team up 43-11 and the defender fell down in pass coverage. He had a 45% completion rate in his time in Winnipeg, and did not even become a full time starter until 1995 in BC, when he threw for 19 TDs and 26 INTs that year, then was let go to Edmonton. He became a back-up specialist in 1994, known for coming off the bench to pull out games, like the Grey Cup that year.
But his passer rating was middling at best. Even in his MVP season in 1999 in Hamilton his rating was a career best 92.4, and he was only over 80.0 four times in 17 years, while being worse than 73.0 eleven times. He only hit 60% in completion percentage once. He threw more INTs than TDs in 11 of his 17 seasons, and only once was his TD:INT ratio better than 2:1.
Now, he was good at piling up passing yards, going over 4,000 nine times. And he was brilliant at avoiding sacks in Hamilton, where 4 times in 7 seasons the team gave up less than one sack a game, including a ridiculous 7 in 18 games in 1999 (credit the o-line and his quick release for that). And he was a winner, having a funny streak of getting to every other Grey Cup (and winning every second time he got there) for his first few years (1990 win, 92 loss, 94 win, 96 loss, 98 broke the streak as he got to the Cup but lost, and then winning in 99 in his last appearance - his only win as a starter).
Bottom line, he was very good but it took more than a few years (and three more teams) after he left Winnipeg to hit his elite level. So it wasn’t an obvious gaffe when we let him go (although I personally was a bit disappointed).
If I remember correctly, it was a contract dispute with Cal Murphy that led to his departure. He wanted starter type money and a starting role which we were not going to give him (and neither did BC for 3 seasons after he signed there) and it got a bit personal, with Cal quoted as referring to him as “that little red-headed piss ant”.
One last story about him I remember. One of the Bombers star defensive linemen or linebackers of the late 90’s and 2000’s (I cannot remember who) mentioned when he was with Hamilton, that McManus would telegraph if it was going to be a running play or a passing play every single time based on his foot position pre-snap under centre, and he was unaware he was tipping off teams to it. Despite this, his sack totals against were astronomically low, in large part due to a standard three step drop and release.
And now you know……the rest of the story.
