I actually expect to see Starks/Soliai on first and second down, with Ferguson coming in only during certain situations (i.e. third and short). Kind of like how Ted Washington was used later in his career, as a space-eating speciaist. Oh, and the oblique is an abdominal muscle - specifically on the side of the body. It can hamper him not just in breathing, but also in his ability to get leverage with his upper body.
