After graduating from Arizona, Miller signed in 1994 playing for the Baltimore Stallions of the Canadian Football League (recommended by Rich Ellerson, his former Arizona coach who once was a CFL staffer) and was a member of the 1995 Grey Cup champion team. Miller recorded a "single" in the 83rd Grey Cup when a punt, aided by a 50-km/h wind at Taylor Field in Regina, Saskatchewan bounded over the head of a Calgary Stampeders return man and out the back of the end zone to award Baltimore a single point.

In a 2003 game against the Baltimore Ravens, Miller completed an 81-yard touchdown pass to Steelers' teammate Chris Hope. This tied a record held by Gary Hammond and Arthur Marshall for the longest pass completion by a non-quarterback in NFL history.
