Sark had had several QBs go pro but have very many actually performed there?
Compare the qbs Sark coached against other schools over the same time period.
Ohio State? Sark's guys have had better pro careers.
Alabama? The few decent pros they've had were Sark's guys. Outside of that, not much.
LSU? Joe Burrow is one, but nobody else.
Notre Dame? Not even close.
Oklahoma? Now we're talking. Kyler Murray, Baker Mayfield, Sam Bradford, Jalen Hurts. Decent careers. Nothing to sneeze at.
My point is, Sark's track record with quarterbacks is every bit as good as the best, and is a lot better than most. It's not so hard to see why a QB prospects with sights set on the pros would consider him. He's proven time and again that he gets quarterbacks to the pros
