In fairness, if you don't watch Redbar and more specifically those who orbit Mike, you'd be unlikely to know what Steeltoe is since they're commentary on commentary that afaik only gets suggested organically sometimes if you're watching Redbar clips on youtube*, and basically Nobody Watches Onions except Redbar (ironic considering the history)...all that to say Racket's sektur and Mike's sektur basically never meet so there'd be no reason without Nick mentioning it that anyone who mostly hawks Nick would think to check for Steeltoe/Rackets crossover.
*This is a bit of an important detail since Mike doesn't do his show on youtube, he uploads on his own website, and the clips can often be weeks or months out of date depending on if Mike is currently at war with clip channels, so regular Redbar watchers, probably the biggest audience that might notice something like this, might not even know about this unless they're hawking NLO or Steeltoe for bring back group related reasons.
