As Gregg Rosenthal pointed out on the Week 8 Recap edition of the Around The NFL Podcast, the third-round draft pick seems to contribute a key play every game.
Arians coached in Indianapolis from 1998-2000, when Harrison was at the height of his powers.
It's a credit to Arians that Carson Palmer dialed Brown's number on a third-down bomb with just 1:33 remaining in the game and five crucial yards needed to move the chains.
"We had three (receivers) at eight yards for the first down," Arians explained, "but when there's a touchdown involved in the play, never pass it up. Don't play scared; play smart."
They can thank Keim for digging deep to unearth a dynamic rookie now pacing the AFC West leaders in touchdowns.
