The exit of GSP and injury to Champ Johnny Hendricks, along with fights already scheduled to determine the next contender(s), leaves a lot of good fighters out of the mix with no hope for a title shot anytime soon. This has the potential to set up a welter weight super series to determine the next challenger; I would argue now is the time to do so as the 170 pound division has never been better. Robbie Lawler and Matt Brown are already matched up, so are Tyrone Woodley and Rory McDonald, along with Hector Lombard and Dong Hyun Kim. That leaves a slew of contenders to sort out, and to give a hypothetical idea consideration, with a long list of middle of the pack contenders not scheduled to fight, the UFC should capitalize on the logjam, with the winner getting a title shot.
The series could have a eight man bracket with names such as  Jake Ellenberger, Nate Marquart,  Patrick Cote,  Rick Story,  Erick Silva,  Thiago Alves  Tarec Safferdine, the undefeated prospect is always an interesting storyline (much like Daniel Cormier became in the Strikeforce Heavyweight Grand Prix), you have undefeated  Kevin Gustelum or Adam Khaliev. The point is there is more than enough fighters. You even have Damien Miaia and Jordan Mien sitting around. Stars also sitting on the shelf include Carlos Condit and Nick Diaz. Even Paul Daley is knocking on the door, wanting back in.
This tournament could add interest to Fox Fight Nights, even carry a PPV main card with all the proposed bouts in one night. The timeline for completion of this tournament would be about a year, year and half, arguably the same amount of time most guys would be away from a title shot anyway, riding a hot winning streak. What about a six man tournament featuring the undefeated of the welter weights? You have  Kevin Gustelum,  Adam Khaliev,  Chad Laprise,  Pawel Pawlak,  Gunnar Nelson, and  Alberto Mina. But also, this would be an opportune time to bring Ben Askren into the promotional fold, and generate some additional buzz to the division.
