I agree that Bradley wasn't the point guard after Rondo went game despite bringing up the ball more times than not. But to state that Bradley didn't have the chances to accumulate assists is just wrong. He was given the second most chances after Pierce to use screens off the dribble and he almost exclusively used them to shoot. That's on him.
Of course that (the
bolded text) would be wrong. I never stated that, of course.
As for the part in italics, um ... not so simple. That's also on his role in the offense. If the D is leaving him open off the pick (because they'd rather guard Green/Pierce/Terry/KG) then any coach almost certainly would want him to shoot.
Bradley actually took almost half his shots (46%) within the first 10 seconds of the shot clock, with a relatively low assisted rate of just 48%, suggesting a lot of them were probably in transition and not off half-court plays. The team as a whole only took 37% of it's shots that early in the clock and over half those (57%) were assisted.
For shots later in the clock, Bradley's assisted rates jump way up (68-75% over the last 10 seconds of the clock)- and are notably much higher than the assisted rates of the team as a whole (59-66%) during those portions of the clock. These suggest that, once in the half court offense, he was playing primarily off the ball and receiving the pass to take a shot.
And frankly, these numbers match up pretty much with what I remember seeing. On fast breaks, Bradley was typically one of the two guys (or the only guy) down the court and often taking the shot. On other plays, even if he brought the ball up, he'd flip it to Pierce and go into his responsibilities moving off the ball, pretty much same as if Rondo was there. If he got open and got the ball his job was to shoot. He was usually no more than the 4th option as well, which means in the half court he was not usually getting the ball early enough to continue the play onward.
