I believe Griese was 17-5 as a starter, which is good for a 77.3% winning percentage. Rick Leach was 38-8-2, which would be 81.3% if the two ties are indeed 1/2 of a win each. Jim Harbaugh slightly edges Leach with 81.7% (working from old box scores here).
“On the offense last year, they had great spacing. That’s what I remember. Great spacing, great shooters, like Nik Stauskas, who’s not there right now. But they always have someone to fill the roles. They have a cutting offense, kind of hard to guard.”
