Well Amare had Gallo, 50%+ from three Shawne Williams, Felton, Douglas, Chandler, Walker, Fields etc all camping out on the three point line, so those are some pretty good options for guys to pass it to in the first half of the season. Especially if they are in the corner, which is the best three to take. So just because he didn't have a player as good as Eric Gordon doesn't mean he didn't have three point shooters he could pass it to when the defense collapsed on him. Too often he would try to force it and take a tough shot, get fouled (positive play), or turn it over.
And Blake had 40 games with at least 4 assists. Amare had 23. Amare's high was 7 assists, which he did twice. Blake did that 6 times, and also had three games with 8 assists, one with 9 and two with 10. Hell Amare's CAREER high is 8 assists, which Blake beat three times in one season. And compared to other PFs playing 30+ minutes, he was only beat out of Boris Diaw last year in assists.
Blake had more assists in his first season than Amare has ever had in his career. Last year Amare's USG% was 30.9 compared to Blake's 27.3, yet still had fewer assists.
