I think the author was nitpicking some. He made an extensive issue of the fact that Walker only took one three (and made it) during the game, using it to explain that Walker isn't confident out there. I can look through Paul Pierce's game log this year and find seven games where he took less than two threes. I don't think we'd question Paul's proficiency in that area. While the point he was trying to make may or may not be true (I wouldn't know, I haven't watched him at Utah), I don't think that conclusion can be drawn from the fact that he doesn't jack it up from beyond the arc enough for the author's taste.
Fouls and turnovers will be a problem, but we could see that by reading the box scores. My issue with Bill Walker getting any minutes at this point lies in the latter - we have nobody on the second unit who can take care of the ball, and he might make it even more of an issue than it already is.
