I could go with Purdy. I would say someone that you could always depend on getting you 1-2 yards for the first down, but over the years you could probably count 2 or 3 people from each team.
edit: can any stat nerds come up with a completion percentage list for forth and short over the past 20 years.
Yeah I think it's Purdy by a large margin. Stanzi made a lot of big throws under pressure but he threw way too many pick sixes
