The real question to me is this.
You have two 330+ pound guys on the field at the same time. Both will get tired. Who is our rotational NT right now? If this is permanent, they have to have been impressed enough by someone to think that he can do a decent enough job as our 2nd string NT.
Toribio, maybe? He's been on our PS for quite a while. Maybe they think that Jolly can do the job, as wel? He certainly has the mold of a NT.
