Bantamweight champion Aljamain Sterling talks to Yahoo Sports' Kevin Iole about his upcoming fight at UFC 280 against former champion T.J. Dillashaw, who Sterling believes is still taking performance enhancing drugs despite Dillashaw's 2-year suspension after testing positive for EPO. Sterling blames inadequate testing methods by USADA and the UFC for Dillashaw competing while "juiced to the gills" and shares his thoughts on how to improve the system.
