First of all, there are many players from Europe in the NHL, so are you acually asking: How should the NHL attract players from England? I'd say the way the NHL has always attracted players = $$$$$$ contracted pay for performance, $$$$$$
I'm not sure that England (UK) has such a big pool to draw from. I say look to Asia. I suspect that right now, there are more Asian players in all of the "North American" sports than there are UK players. I also want to I pont out that these Asian players seem to adjust well to the sports in question. In basketball we have Yao Ming in basketball, Ichiro Suzuki and Wang playing baseball. For hockey there is Paul Tetsuhiko Kariya, Richard Park, Jim Paek,Larry Kwong,Yutaka Fukufuji,Hiroyuki Miura
to name a few. So for me ,it makes more sense have the NHL season kickoff in places like Hong Kong and Tokyo rather than London.
