Olynyk is nothing like mchale. Mchale is a true pf, long arms, tip in, power shots in. Olynyk is a stretch 4 in the mold of brad miller. In the nba he wont be effective any other way.
Brad Miller was anything but a stretch 4: legit size, strong, willing to do the dirty work around the hoop, great rebounding ability, decent defensive instincts around the hoop.
Did you miss the non-washed-up version of Brad Miller somehow?
Are you serious? The guy while a better rebounder than olynyk or olynyk may ever be, was majority of the time a faceup player. He had only half the post moves olynyk has now and only spent 25 percent of the time initiating his offense from down low.

In my book, a stretch 4 is someone who can't guard centers, and is limited to long jumpers offensively.
Brad Miller, in his prime, was decidedly not a stretch 4, given that he was fully capable of guarding most centers in the league, and took roughly half of his shots from within 10 feet (most said half were taken at the rim).
Also, the jury is still out on whether Olynyk really has any post moves that will work in the NBA at all.
edit: For a textbook definition of a stretch 4, check out Raef LaFrentz's 05-06 season with the Celtics (3/4 or so of his 500+ shots from outside 16 feet, 70% of shots at the rim were assisted).
