This was likely the secret sauce behind the 1980 Olympic hockey team win. That was not a collection of NHL superstars on a two-week "vacation" but a real team of motivated amateurs (kids just out of high school) put together by the late Herb Brooks and they practiced together for months and months. A true team.
Brooks was right about one thing, though: He said from the start that he didn’t want the BEST players on that team, but the RIGHT players.
Kids just out of college... and most of them with NHL contracts and delayed reporting dates.
