He isn't 60% Rubio.
I don't understand how people aren't happier about this add with what he is showing to this point. As you just mentioned, PGs need time to get acclimated to new players. While that is happening he is clearly fitting in and feels comfortable within the offense finding spots to score and especially comfortable within the defense with the towers and size behind him.
Cavs have a 94.8 DRtg with Rondo on the floor to this point, which is ridiculously good considering the Cavs just played 2 top 15 offenses according to NBA.com's ORtg and he is new to the team. Yet in here and around the board we had people telling us he is "cooked" defensively.
On top of that, his per 36 and per 100 numbers with the Cavs are pretty much Rubio's exact numbers to this point. He is turning the ball over at a higher rate, but again, PGs who are asked to run the offense need some time to get used to new players and their spots/tendencies and that can easily be pointed to as a reason for that higher tally.
Obviously I doubt the 3 point % on that volume remains 40% plus, but we just watched him have a 20+ game stretch last season where he shot 43% from 3.
I am thrilled with what we are seeing through 3 games. It's clear the dude fits much better with the Cavs than the Lakers and he hadn't played an NBA minute since 12/23 until the Blazers game so I am sure he is getting his legs and wind back under him, and things should only get smoother running the offense as he plays more and more.
We got this guy for free. Love the fit and think it'll only get better the more he plays with guys.
