According to the Rookie Scouting Portfolio, he would have been 4th round grade at tackle, and first round at center. So that at least suggests some versatility this year with likely a long term goal of him replacing Mack next time his contract is up.

Mack's contract does indeed include an opt out clause after 2015...
