Well ... I guess we'll see what happens against a team not named the Wizards, but I like the fact that Brandon is taking it upon himself to lead by example, which will hopefully get people playing a more committed brand of D.
Frankly I think the biggest problem has been Nate getting these guys to buy into the scheme and trust that if they give it the level of effort he's asking for that success will flow from it; it's like they have been getting caught half-way between fully committing to the paint and running out on shooters so the end result has been a bad blend of getting killed in the paint and killed by perimeter shots.
One would hope they Wizard game would illustrate just how many easy transition buckets lead from defensive rebounding and pressuring guys on the perimeter as well as packing the lane, rather than having to grind in half-court sets all the time.
