That's not too bad, just stick with it. Check out this losing streak: 2-11 in 13 fights with a 7 fight losing streak, I was FREAKING out. There's a thread about it somewhere in the General Help forums. Anyway, now he's the GLORY LW champ.
On the other hand, Powell might be experiencing the dreaded late-career collapse, like Hector's guy Vega did, or like my fighter Lupus. It hurts to watch him just fall apart like this, I'd rather he retired.
