The Facts: If the Cardinals, as expected, take their time and slow-play Kyler Murray’s eventual return from major knee surgery this upcoming season and veteran backup Colt McCoy, who has had a recent string of injuries and for some reason can’t maintain the starting quarterback position, do the Cardinals have a potential “Brock Purdy solution” on the roster? The answer just might be yes, and it could be Tune, Arizona’s somewhat surprising fifth-round selection in this year’s NFL draft out of the University of Houston.

Diehards Line:Purdy’s meteoric flight from going to “Mr. Irrelevant” to NFL stardom was one of the league’s most captivating stories a year ago. But could it happen again this soon with a new face in a new place such as Arizona? Is Tune, the 6-2, 220-pound prospect from Plano, Texas, capable and possibly in the right situation to pull a Purdy and unexpectedly lead Arizona to some potential early-season success? We’ll get a closer look perhaps later this week when the Cardinals hold a three-day rookie minicamp at their Tempe training facility Friday through Sunday, but there are no guarantees, obviously. It's important to remember that Tune would clearly have to climb his way up the Cardinals’ depth chart to even have a chance of taking the field. At present, he’s not only behind Murray and McCoy, but probably and most likely, also behind holdover David Blough and perhaps even Jeff Driskel, the former sixth-round pick by the 49ers in 2016 who signed a one-year deal with Arizona last month. If coach Jonathan Gannon and offensive coordinator Drew Petzing decide to make it an open competition until Murray returns, however, it could be any one of the four. ... We'll be watching for more.
