As for an examples, Jon Olav Einemo hadn't had a fight in over 5 years yet he was given a UFC contract. Granted he was a former BJJ World Champ, but 5 years is a long layoff.
Christian Morecraft only went 6-0 against journeyman, inexperienced opponents, & downright cans before his UFC debut.
James McSweeney was 3-4 before he was given a chance on TUF, won at the Finale to bring his record to 4-4, & then got 2 more UFC fights.
It doesn't take a lot to be given an opportunity at HW.
