There was nothing flashy about Curt Giles' game, but NHL teams need players who are defensive stalwarts, a role he played very well. 

Is this rank too high or too low?

If you think it is too high, it may be because you are pointing out that Brett Hull was only with the Dallas Stars for three seasons, a relatively short period compared to many on this list.  While he was an All-Star once in Dallas and was still certainly productive, he was not putting up the exact explosive numbers he did in St. Louis, where he led the NHL in Goals, three of which were 70-plus.  His highest goal-scoring season in Dallas was 32.

Prior to joining the Minnesota North Stars, Gilles Meloche lost a significant number of games as the number one Goalie for the California Golden Seals (later relocated to Cleveland as the Barons).  This was not a testament to Meloche’s ineffectiveness; instead, he played for some bad teams and was not regarded as the problem.  Cleveland’s merger with the North Stars allowed Meloche to play with a better team, and he would finish in the top five in Wins twice.  He would also attend the All-Star Game twice and would finally make it to the playoffs with Minnesota, where he had a winning record of 21-19.

Cesare Manigo may not have been an elite Goalie in the National Hockey League, but he was a workhorse backstop who became successful in the expansion era.  Maniago may not have brought the Minnesota North Stars to the Finals, but his defensive skill brought them closer to the Holy Grail of Hockey than they probably deserved at the time.
