I wouldn’t assume Raheem Mostert starts. Once he does, it will be the first start of his career. As dominant as Mostert was toward the end of the season, Kyle Shanahan and Bobby Turner liked starting games with Tevin Coleman because he’s a little bigger and more physical runner than the others.
So my guess is that the arrangement will be the same as last season: Coleman starts, with Turner then using his feel for who’s hot that day dictating the snap loads for the rest of the game.
The wild card, of course, is McKinnon, the author went on to say. It’s possible that he becomes the preferred tailback on third downs. There also could be instances in which he and another tailback are in the formation with McKinnon lining up in the slot or even out wide. The story added if McKinnon's knee isn't as good as the early reports, Wilson enters the picture.
