Like other promising hockey-playing kids in Kladno, Czech Republic, after 1991, Frolik drew the inevitable comparisons to Jaromir Jagr. During his teenage years playing in his hometown, Frolik was even nicknamed "Baby Jagr," both for his physical and on-ice similarities to Kladno's biggest hockey export.

By the time Frolik was selected by the Florida Panthers with the No. 10 pick in the 2006 NHL Draft, Jagr already had won five Art Ross trophies, a Hart Trophy, an Olympic gold medal and two Stanley Cup championships.

To acclimatize himself to the North American game and culture, and at the urging of the Panthers, he made the jump overseas in the fall of 2006, joining Rimouski of the Quebec Major Junior Hockey League. Two years of seasoning later, he was ready to make the move to pro hockey.

Following back-to-back 21-goal seasons to begin his NHL career, Frolik was traded to the Chicago Blackhawks midway through the 2010-2011 season. Two years later, in the spring of 2013, "Baby Jagr" would lift the Stanley Cup, just as Jagr had in 1991 and 1992 with the Penguins. Frolik had 10 points in 23 Stanley Cup Playoff games in 2013.

That offseason, Chicago traded him to the Winnipeg Jets. After consecutive 42-point seasons, Frolik signed a five-year contract with the Flames in the summer of 2015.
