I have a problem investing heavy money on a soon to be 29 year-old. If he's allowing dribble penetration now, what will he look at on a 5 year deal between the ages of 29-34?
All point guards allow dribble penetration.
Just like all point guards miss free throws...Rondo at a a higher rate than others in both though.
Ok, so how high is Rondo's rate of allowing dribble penetration, and how does it compare to other point guards?
What do your eyes tell you?
Pretty much that you make things up without having much of an idea (if any) whether they're true or not. I missed last night's game but I just watched much of it on the dvr, checking Rondo's defense. He spent most of the first half guarding Teague, who was largely ineffective. He rarely got into the lane, and mainly did off of picks. He beat Rondo off the dribble once to get into the lane. He got into the lane as often against Bradley as he did against Rondo, even though Rondo was covering him 3-4 times as much as Bradley was.
The second half seemed similar. He got beat off the dribble a couple of times, and players he was guarding didn't get into the lane that often, and when they did it was generally off of picks. He didn't do any worse of a job of keeping the guy he was guarding out of the lane than any of the other Celts guards, or any of the Hawk guards. Overall I'd say that guys he was covering scored 4 or so baskets and players he switched off of on pick plays scored a couple more. He had some turnover issues, but his defense wasn't really a problem. It was worse earlier this year but it's been better recently.
Again, though, how does that compare to other point guards? How often do players get into the lane when they play against Paul, Parker, Lowry or Deron? How many of those times are from picks, and how often do those guys get beat off the dribble? How about Conley, Curry or Lillard? I generally judge how well Rondo does in terms of allowing dribble penetration by comparing how often he gets into the lane to how often the guy he's guarding does, and on the occasion that I watch non-Celts games I just generally notice it in terms of the players doing overly well or poorly in defending their opponents.
