Frank did struggle in his last fight. He looked amazing vs Michel Rivera (Showtime headliner), stopped Jackson Marinez (Showtime fight), and won the only time he headlined an FS1 show vs another undefeated prospect. Anyone who headlines a Showtime card is on the brink of making the jump to ppv's (especially as the B side).
Tank isn't going to fight anyone outside of PBC's roster. That's the reality until Teo is allowed to cross the street, or Ryan wins enough that the public demands that fight. I see zero interest in a Shakur or Devin fight (even though I would buy those PPV's in a second).
Also, I'm a high school teacher and was teaching. I wasn't aware Sherdog Forums had a reply time I had to conform to. I check this site on my lunch break and maybe one other time a day. I make no apologies for replying to you on my schedule.
