The Facts: After springtime’s worth of reports alerting us to Arizona's rookie receiver "blowing everyone away" and drawing "favorable" comparisons to Colts burner T.Y. Hilton, Brown is off to a hot start at training camp. "I can tell you so far we haven't been able to cover him," said Cardinals GM Steve Keim on Monday, per ESPN.com's Josh Weinfuss.

Diehards Line: The third-round pick out of Pittsburg State has drawn parallels to Hilton because of their similar size and identical 4.34 speed. The 5-11, 179-pound Brown is a candidate to leapfrog Ted Ginn as a deep threat alongside Larry Fitzgerald and Michael Floyd in three-receiver sets. As NFL.com suggests, it's notable that a rookie is excelling against a talented trio of Cardinals corners in Patrick Peterson, Antonio Cromartie and Justin Bethel, but Keim acknowledged he wants to see Brown do the same in pads. And his first reception in pads? Brown beat Bethel for 80-yard TD. ... Can't hurt to get him on your radar.
