I have the game we played against Louisville on DVD and he was dominant in that and crucial in the outcome. In limited viewing his stats don't really reconcile with what he looked like, so maybe you are right about it being a coaching decision.
I just looked it up and he only avged 7.9 mpg as a senior. That seems really weird. Wasn't a very deep team and basically 6 guys played almost all the minutes, but he got about the same playing time as Dwight Moody that season.
Here is an article about him from a game against KSU:

And 6'4" junior Guard Michael Walker, a physique-alike for that other Walker, the football guy from Georgia, may be the finest eighth man in college history.
Walker positively destroyed Louisville a few weeks ago, and he wreaked the same havoc on Kansas State. The Wildcats were leading 20-13 with 7:39 to go in the first half, but their relentless pounding of Missouri had put their front line in foul jeopardy, and when Walker entered they were forced to cope with one of the few Tigers as rough as they are. Soon Stipanovich and Walker had Missouri back in the flow, and the Tigers took the lead 25-24.
Kansas State had no excuses at the beginning of the second half, however, when Sundvold, who finished with seven baskets and four assists, personally realigned the strategy of the game with three bombs over the zone. His club behind 37-30, Hartman called time-out and ditched the zone, after which K-State clawed back with a tight hen-to-hen defense. Also, the Wildcats scored seven unanswered points.
Shortly thereafter Missouri called time-out, and in the huddle Stewart ordered that spectacular alley-oop to Bridges. "I throw it anywhere in the building, he'll get it," said Sundvold. Which the Prince of Clean Air did. And now the Wildcats, getting no offensive aid from the usually consistent, 15-point-a-game Tyrone Adams and struggling with inexperienced freshmen, appeared to be in chaos.
Stipanovich, who ended up hitting nine of 11 shots for 20 points, and Walker, who was four of five from the floor and had three assists, continued to be effective as Missouri increased its lead to 51-43 and then went to a spread "layup game" offense with 8:05 to go. Obviously the battle was over, and Mizzou, the nation's second-best foul-shooting outfit (.778), would play out the string at the line. Well, uh-huh. The game was over, and that marvelous old sour lemon, Hartman, knew it.
Miraculously, K-State still had a chance when two 'Cats trapped Sundvold at midcourt. But the Tiger quarterback spotted Stipanovich all alone and hurled him the ball. Stipo dunked for the clincher with 22 seconds remaining. "All I could see was a bunch of purple numbers coming after me," Stipanovich said of his final effort.
But for at least one more week the Tigers were still unbeaten. The only number that mattered to them was No. 1.
