Let's start by remembering that Stieb was the top pitcher (by WAR) in baseball for a few 3-year periods in the early 1980s.
From 1980 to 1985, Stieb totaled 36.5 WAR. By comparison, Jack Morris' highest 5-year period was 1983-1987 with just 20.1.
The news for Jack Morris just gets worse after that.
Here are the leaders, by WAR, for all the the 1980s:
Stieb was first by a mile. Admittedly the timing of his career happens to line up just right with the decade. But check out how Mr. "Best Pitcher of the 80s" and "Future HOFer" is just 12th in WAR with a 109 ERA+ that pales to Stieb's 127.
Stieb's reputation was hurt by his injuries that coincided with Toronto's rise. He had a good but short season in 1991 followed by a bad, short season in 1992 as the Blue Jays went on the win the World Series. Then he had a very short, very bad season with the White Sox in 1993 as the Blue Jays won again.
I chose this card for Stieb because I like it, but also because of an oddity. If you look at the photo on the front, there's a darkened rectangle around Stieb's head. You can see it most clearly to the left of Stieb's head, over his shoulder, and to the right of his head, through the batting cage. It looks perhaps like a reflection on a piece of glass that the photographer was shooting through?
Also, check out the uniform that Stieb's wearing...the Blue Jays are going back to this look in 2012!
