I don't think that Eliot Marshall is a can. He had a close fight with Matyushenko and has a win over Jason Brilz who people consider to be "underrated" because he stylistically matched up well with Lil Nog and lost a controversial decision against him. Although Eliot's performance against Cane was terrible and he did look like a can. He just seemed to be too afraid of Cane's power to fully commit to his take down attempts which didn't work out too well for him either way. He's not a good fighter, but he is a step above can in my opinion.
Cane probably won't be fighting for the title any time soon, but he should continue to secure his spot on the UFC roster if he keeps having performances like that. There is nothing wrong with not being a title contender. Guys like Leben, Kongo, Stephens, Lytle, Bonnar, and among others are all popular fighters that probably won't ever touch UFC gold, but deserve to be in the UFC and are big names. If that were Cane's future, it wouldn't be a bad thing.
