The key is explaining. Throw up top ten lists and compare the players. There's plenty of time to show graphics that would help people understand previously unheard of stats. A QB rating means nothing unless you see them repeatedly and realize what the better QBs would have. Likewise, if you never heard of OBP you might think a .315 OBP is good, because you think a .315 AVG is good. The first time you see an OPS, you have no idea whether 750 is good or bad. But if people keep showing it, and giving examples of good, bad or average, others will learn. What's not helpful is whiny coots telling people there's no place in baseball for these stats. I can't disagree. Why would anyone want to simply exclude something from all discussion? Even if it's a stat someone came up with that ultimately proved to be of little value, at least talk about it and come to that conclusion before simply lopping it off at the head.
