Sandhagen can't get someone ahead of him in the ranking.
Waiting for the TS is dangerous with Sterling, Dillashaw, Cejudo, Volk and Garbrandt hoping for that same shot, he could be stuck in a Leon Edwards situation. Might as well get someone with namevalue, not too risky and who won't pullout.
Rob Font = Dangerous, no name value
Jose Aldo = Name Value but more dangerous than Edgar
Pedro Munhoz = no name value at all
Gabrandt = Name value but not available and dangerous
Other are booked
Edgar has name value, won't pullout and is not much of a threat IMO
