As Legend already pointed out, LOB got an Unsportsmanlike Conduct penalty and not an Instigator penalty. When they came back from the TV timeout and Nash and McConnell were saying that LOB got the instigator, I was surprised because I was pretty sure that Manson's glove(s) were off first. So I went back and rewatched the play a few times. Sure enough, it looks like Mansons glove(s) came off first, so why did LOB get an instigator? Upon closer inspection, it looks like LOB actually pulls Mansons glove off him and I believe that is why LOB got an Unsportsmanlike Conduct penalty. This is just like pulling another players helmet off during active play. Had LOB just skated up to Manson and challenged him and Manson obliged, I don't think LOB gets and extra 2. Still a dumb move by LOB, but not the true instigator penalty per NHL rules.
