Re: Zone or Man to Man D against fast, black, athletic youth?
This post comes across as racist. The only reason you would write about your opponent's skin color in both the title and post is if you think it makes a difference. It doesn't matter if you think it's positive or negative, still comes across as racist.
Ignoring that... try both out and see if zone works. If not, switch it up. They'll likely show you pretty quickly what they have a preference for.
