During Howe's first 14 seasons:
Toronto dynasty (1947, 1948, 1949, 1951);
Montreal dynasty (1956, 1957, 1958, 1959, 1960);
Howe "only" won four cups during that span.
EDIT: Twice during his first 14 seasons he led the playoffs in scoring in a losing effort and twice more against a Leafs dynasty in the 1960's.
Are we really going to count 49-50 as a SC Howe won though?
He played in a single game and his only contribution that can be found was an effort to after Teeder that ended in drastic fashion for Gordie.
Flashback: Mid-game accident left Gordie Howe close to death
We don't have a complete and totally accurate picture for Gordie Howe but there is strong evidence to suggest that he was playing Jagr type plus MPG in the late 60's which sheds light on 2 things.
One, which we already know, in that Gordie was an incredible physical speciman who had great strength and was a great athlete to play as long as he did.
The other was that part of his ability to finish top 5 in scoring so often was that he was given more ice time than some other stars both 5 on 5 and on the PP.
Take 1968-69 for instance.
Howe was on the ice for 134 GF Detroit scored 221 goals so he was on the ice for 61% of the goals the Wings scored. He was also on the ice for 35 of the teams 40 PPG
His center Delvecchio was on the ice for 123 GF Detroit and he was also on the ice for 28 of those 40 PPG
2 other stars of that season also had lower ratios, the most telling is Jean Beliveau who was on the ice for 102 of Montreal's 271 GF ((38%) and 28 of Montreal's 43 PPG
For Mikita it was 126 of Chicago's 280 GF and 39-56 for the PP.
Of course there is a difference in the makeup of each teams rosters but I would bet dollars to donuts that if we had Howe's TOI it would reveal that he played more than even the average elite player which in part goes to his scoring totals.
Of course the game speed of play in the NHL in that time period is also quite different and more receptive to any player playing longer MPG than post lockout.
There is no doubt that Howe belongs in the big 4 but we also have to acknowledge that simply comparing counting stats and placements between the 50's and post lockout are like comparing apples and oranges.
