Depending on how you look at it... I think Martinez's completions were a record on Saturday for completion percentage with a minimum of 20 passes. The prior record was Dave Humm at 23 of 27. Adrian's cousin Taylor still has the overall record at 13 for 14 (this game was when Bo had his health scare and Papuchis led us to victory over Gus Malzahn).
