Why do so many feel Journey needs Perry to get airplay?

Some people on this forum think Journey might only stand a chance for airplay if they had Perry again, but w/out him, they have no chance. I don't get it. Why would they only have a chance if they had Perry? Back in the day when they were getting airplay, most people didn't know who Perry was anyway. I know a lot of people in my age group who like the big Journey "hits", who would & do buy a Greatest Hits album, go to a concert when the band comes to their town, but when I say "Steve Perry" they look at me blankly. They have no idea who he is.
Jeff has a fantastic voice, a great stage presence, he's intelligent & funny. If Journey gets some publicity, he will come across really well. Since he looks so darn young, he will not be taken as a guy who's been around forever (even tho he has). He stands a really good chance to attract the youth of today to the band.
I love Perry & I'd love to hear new stuff from him. But I just don't understand why so many say Journey needs him in order to get airplay. If they can't get airplay w/Jeff using the right publicity, then they couldn't get it w/Perry either. This doesn't make any sense.
