Wilkinson started the last seven games of 2018 at RG.

O-Line coaches start their best five shuffled to their best spots. If one of the five can't go, they usually bring in number six and reshuffle, if necessary.

In view of the fact that Wilkinson started at RG last year, I think they'd put him there if Leary can't go. Seems Schlottmann is number seven at the moment. If a T was needed during a game, a shuffle would probably happen.
