I watch the Hawks a lot, and I like Schroder, but he's a worse PG than both Knight and Bledsoe.

He's also playing below replacement level on the year.
His assist % is higher than both but his turnover % is in between Knight and Bledsoe, and there's a huge gap in true shooting %. I also see the Hawks message board rail on him for stupid plays all the time. When you factor in his supporting cast relative to what Bledsoe and Knight have in Phoenix, I'm not at all convinced he solves the problems people clamor about on this board.
On the plus side, he's 22, which is a significant gap in age over Bledsoe, and he's on a rookie deal unlike Knight. Like I said, I like him, but he has a long ways to go, and his athletic potential is beneath both Bledsoe and Knight in my opinion, despite his elite speed.
