I also think the zone is not what it used to be. Every kid growing up these days focuses on shooting 3s more than they shoot any other shot. And lots of kids can hit them (except for ours on certain days oddly enough). And there is enough tape out there for teams unaccustomed to playing us to figure out how to successfully beat ours.
We've been lucky pulling a couple games out this year against less talented teams. Teams we would have beat going away in years past. Something needs a refresh. Feels like our recruiting at least has turned for the better, again, except for centers.
