I think it's about managing your good fighters. In the UFC and with the US audience it's essential to have a good record and not to go on a losing streak. With the fighters they want to keep, they can't put them into a really competitive fight right after a loss, because anything can happen, and two losses in a row is a huge question mark. One minute you're 'not human', and the next minute, according to 'those internets', you're the biggest can that ever walked the earth and couldn't take a paralyzed grandmother.
So it makes sense to let him have a tune-up fight, if only to pad his record out with another win.
Although, I, too, maybe stupidly, don't think this will be totally one-sided. I always liked Chirs Lytle.
