To force or not force baseline is simplistic. It's beaten into guys heads never to get beat baseline and you certainly don't want ballhandlers getting underneath the hoop while trying to use the baseline as a 'defender.' I generally agree with that because once a guy is all the way inside easy buckets and fouls follow. I'm also not sure you have to have a hard rule about this. Like, I wouldn't force a guy baseline if he's going with his strong hand. I'd always want to force a guy to his weak hand and let him make a play he doesn't want to make.
The first help defender only needs to be quick in his rotation. The guy who got beat either doubles or slides. It's the other 3 guys who need to complete the D. In this exact scenario, the Bulls are great. The wing penetrating quickly finds himself covered by a big, his outlet passes inside are covered, and he's got to find somebody on the perimeter. When we do it it's a horror show of guys lost in space. So I don't really get the whole, "just force guys baseline" argument.
