Great take. I particularly enjoyed how you gave Bonner some credit; his defensive prowess is highly underrated on this board. The fact that people put him and Finley in the same sentence baffles me; Bonner's defense really is good enough if his role in the 20 or so minutes I think it will be.
Ultimately, our defense is a work in progress. However, regardless of how much we can improve, I think we defended the initial possession rather well tonight, maybe better than we ever did in all but a few choice games last year. The fact that we were that good this early is only a good sign.
I think people are confused as to why Bonner and Fin are getting the roles that they are at this point of the season. In fact, I think Pop may be right in starting them, at least for now. Bonner's situation has been spelled out already; Blair needs Dice to check his defensive inefficiencies and Bonner helps Timmy offensively. What people need to remember is that this is not an insurmountable problem in the rotation caused by the downsides of our talent. Blair has great defensive potential, particularly against bigs with high centers of gravity . Remember how the Lakers frontline got wrecked by the very small Rockets frontline? Bigs with high centers of gravity lean on their defender when making their post dribbles. When you have a smaller guy like Blair guarding them, you ruin their balance. Add Blair's length, great hands, high basketball IQ, and superb positioning, and you get a guy who has terrific defensive potential.
As Graydon Gordian said in the Daily Dime recently:
Blair was a great defender in Pitt (though foul prone). I have confidence that he can at least become a serviceable one by the end of this season. If he does, a lot of our rotational problems are fixed cleanly. But lets suppose he doesn't, which is also possible, what do we do then? Well, we live with greater minutes for Bonner. The onus is on Blair to improve; you can't get minutes for the Spurs without better defensive efforts. The fact that he is so passionate about defense is a great sign.
But now the question is, why does Pop start Finley? I think its rather simple: he'd prefer to start Manu but is afraid to injure him and he views Roger as a player more suited to be off the bench. Finley was hot in the preseason and Pop wants to ride that wave at the very least. The reason why Roger is a better player off the bench is that Finley has a hard time contributing in spot minutes, and Roger can also shoot off the dribble really well. Roger can create his own shot and Fin can't; the starting lineup has plenty of guys who can make plays so he put Roger on the bench so he could best use his abilities. Fin is also used to playing big regular season minutes and Roger much less so, as seen by how Roger wore out as the season progressed. Also, I don't think he considers Roger to be a much better defender at all, so the defense lost, at least to him, isn't much.
