I was going to say something along the lines of Terfu. Also in the same vein, I was also going to reply to this before he posted. (my post lagged out i guess)
Any team can have a good defense, but its the SB(especially at the C position) that makes the 2-3 successful. As I mentioned before, the C position will defend the majority of the driving layups and dunks in a 2-3 defense, which there are tons, so you have to have the SB to make it most successful.
you are saying that the 2-3 is even worse than M2M versus a LI, and that is the exact reason SB is important.
i think 2-3 zone is so bad in part because it lowers OD so much. i've faced a number of teams with really high shot blocking & 2-3 zone... they were
terrible though. 100 times worse than the teams without high SB. sure, there's other factors, but still... as much as you're touting SB they should have been much better? (unless, of course, those other factors are really the key & SB only plays a minor role)
Which the high driving lower IS will need the SB while the low driving and high IS will just need the good ID.
When I faced a lot of those high SB teams, I had ridiculously low IS. Of course I'm aware that in and of itself proves nothing.
