Historically speaking (or, at least as far back as Ourlads' data goes, which is 2008), that 59 miles per hour stands up pretty well. Only two quarterbacks hit 60, Bryan Bennett (then of Southeast Louisiana, now of the CFL's Winnipeg Blue Bombers) at the 2015 combine and Logan Thomas (then of Virginia Tech, now of the Miami Dolphins) at the 2014 combine.
It should come as no surprise that the two quarterbacks to follow Lynch in terms of pass velocity were two expected to be selected in the first round of the 2016 NFL Draft, Cal's Jared Goff (58 mph) and North Dakota State's Carson Wentz (57 mph). Penn State's Christian Hackenberg, Wisconsin's Joel Stave, North Carolina State's Jacoby Brissett and Liberty's Josh Woodrum each hit 56 miles per hour.
It should be noted that a good number of former first-round selections opted not to throw at the combine over the years (Teddy Bridgewater, Blaine Gabbert, Robert Griffin III, Andrew Luck, Johnny Manziel, Matt Ryan, Matthew Stafford, Ryan Tannehill and Tim Tebow each did not throw in Indy). So, take these numbers for what they are ... good, clean fun.
