After skimming through this list, you won’t be surprised that Brandon Weeden completed a program-record 565 passes in 2011.
Second on that list is Weeden’s junior season in 2010 where he completed 511 passes. For more context, in Mason Rudolph’s best season, he completed 489 passes (though Rudolph does have the program record for passing yards in a season).
Now let’s get to the most single-game completions in OSU’s history.
