If you have watched, we are not that bad either. Team is shooting right at a 40% clip from 3. I'm not saying were above average because were not, just saying don't buy into the whole "they can't shoot it" theory. Can they come out and go 1-20 from three? absolutely. They have also shot over 50% from three in several games this season.
Also, with the zone concept, its not like a road block. Where you put the "closed" sign in front of the lane and automatically he will look for a detour, which is chucking up shots. He will still find ways to penetrate the zone, or at least try. Which leads to my next point....
If Wall and Bledsoe (which both have done this season) continue to go head first into the lane trying to spin and juke (football term... yes), and turn it over then we have a problem. Bledsoe has shown the tendency to do this more than Wall, trying to do to much with the ball when its simply not there.
Its going to be interesting to see how it all plays out.
