I think LJ is gonna be banged up all year, & I think ARod understands Sione & Nawahine have more upside than Ropati. Sione is freakin durable, too.
If Haunga were a faster guy he could be our main back — but even then we'd still give a lot of carries to a big guy like Sione.
I say this as a guy who LOVES Haunga. Kid is a big-time playmaker.
