Hypothetical question... Do you think the NBA coaches(not only the best ones) would be successful with European Teams in European leagues?
If you think the answer to this question is yes, then you have really really no idea about European Basketball or the European coaches.
I'd bet on my life that half of the NBA coaches couldn't even crack the top three with a European team in the leagues like Spain, Lithuania, Turkey, Russsia etc. They could do maybe only with star-filled teams like Barca etc.
And the notion of "NBA coaches are better because they are in the best league" is one of the most ridiculous allegation I've ever heard in my life, so I don't even try to discuss against it.
Heck, I wasn't gonna post in this thread once again after I saw how people are actually biased, but I'm going with this mistake for the last time with this post.
Now I'm off to work, by your leave.
If you'd bet your life on something so trivial and completely possible to lose then you may want to second think that.
I think several coaches would be able to run a Euro team with success. A few retired coaches would excell as well.
