I think that's why they got Meredith, who would essentially back up Butler next year, assuming the plan is to keep Butler at RT.
They could always move Wood to C with Hangartner backing him up, Butler back to RG, then drafting a RT to either start or to compete with Meredith.
I'm sure everyone agrees that we need to address the LT position, because as it stands, Bell hasn't been the answer, however that could change with improved play the 2nd half of the season.
