After starting the 2008 NLL season with an 0–5 record, the Rush fired the franchise's original head coach and general manager, Paul Day, and replaced him with former NLL Coach and GM of the Year, Bob Hamley.

The head coach of the Edmonton Rush however, has come under fire by the Calgary Roughnecks.

The rivalry heated up March 13, 2009 in Edmonton as Calgary built up a 14–3 halftime lead over the Rush.

At the one second mark of the 3rd quarter, a line brawl broke out between the two teams resulting in nine fighting majors and nine misconducts.

[8] Edmonton did get the upper hand in the first playoff meeting between the teams as the Rush won 11–7 in Calgary on May 1, 2010.
