I wasn't active in comp back then, but didn't Jackiechan only play like a year on EU before going to NA? Surely Cazasar could take his place, because of the impact his leadership had on team GER .
I think he played in the first Team Germany in NW. After that he never played again in the team, except one time, when he stayed in Germany for some months, but went inactive after some time, so he didn't really play in it. So yes I think you might be right with that, he played roughly one year in EU. Cazasar instead played several years with us and with him as captain, Germany even won one NWWC. He probably wasn't as good as Jackie individually, but under the following categories "gamesense and awareness, the ability to teamplay and communicate", Cazasar really was one of the best Germans in that regard.
