Following Mularkey's dismissal, Miller landed a coaching job with the Berlin Thunder of NFL Europa in 2006.

In 2007, Ken Whisenhunt was named as head coach of the Arizona Cardinals and offered Miller a position on his staff.

Also in 2008, Fitzgerald, Boldin and Steve Breaston each gained over 1000 receiving yards, a feat only accomplished five times in NFL history.

Edinboro's offense led the country with 80% completion percentage and set single season reception record.

Under Miller, Bethel-Thompson threw for a CFL-high 4,731 passing yards during the regular CFL season and helped lead the Argos to an upset victory over the Winnipeg Blue Bombers in the 109th Grey Cup.

During the 2022 & '23 Argonaut training camps, Miller developed Canadian College QB, Taylor Elgersma.
