I went with Manu, but I don't have a problem with Crawford winning since he didn't start 20+ games. (He started none.)
He was a far better offensive version of Ronald Murray a year ago, and gave the Hawks more choices in the backcourt and on the perimeter in terms of lineups. And while Crawford is getting too much credit for the Hawks moving up to the 50-55 win range (Horford's continued development and Josh Smith finally becoming a good player mattered more) it was a good addition. (Not that anyone thought it was anything but a good move before the season, or at least I don't remember it.)
It is another example of "play at least 30 minutes, get around or more than 15 points and play on a winning team and you'll win in a landslide." Actually being a combo guard (or swingman?) is a pretty good indicator too. Looking at the winners of the last decade, outside of Corliss Williamson's fluke season and Antawn Jamison's lone benching ever winner is a combo guard or whatever you think Manu/Mike Miller are.
Other than Aaron McKie you also have to go back to 1995 to find a winner below 13 ppg.
Crawford won the award going away with 580 of a possible 610 points, including 110 out of 122 first-place votes. Jason Terry(notes) of the Dallas Mavericks, last year’s Sixth Man winner, finished second this time with 220 points. Anderson Varejao(notes) of the Cleveland Cavaliers (126 points) was third.
Odd that Manu didn't place, Varejao placing so high is surprising as well. (I was just looking at the voting, and it's usually 90% guards/scorers.) Even though he picked up more win shares than Crawford in about 300 fewer minutes.
