So did Derek Ryan, and Randy Gregg, etc.
I get what you are saying, but VERY few players make it to NHL after playing CIS.
I counted 18 Golden Bears alone that made it to NHL games played since 1970. With the rate increasing in recent years.
While not astounding, that's just the Bears. Theres of course many more ex CIS players that managed to make the NHL.
But CIS players tend to be a different breed. Randy Gregg typifies that. he could have continued to make millions in the NHL, but went into his Pediatrician practice instead which was his dream all along. He just wanted more in life than being a hockey player. His dreams were bigger.
Recently Jordan Hickmott could have played in the NHL, was good enough, was drafted BEFORE playing CIS, but wanted a degree. He had another go at the AHL but gave up quickly to play in Europe. For a lot of guys that have other career ambitions other than hockey it makes much more sense to play in Europe, have great memorable experiences abroad, vs toiling in Peoria in the AHL. For these players, they don't see putting in several years trying to get into the NHL, so they don't. They go to Europe for quality lifestyle before settling into the career they aspire to.
When you listen to CIS players many of them want to play in Europe for awhile as a well paid life experience. Kind of a backpacking Europe thing except good pay, and for longer than a year. They often settle in there for half a dozen years, then call it a day well before they hit 30 and go onto their career.
If more CIS players had the NHL fever more would get in. But so many, given the choice between AHL, and ECHL and Europe, pick Europe.
