I really don't see many people parading around claiming him to be elite. Maybe in the comments section of Sportsnet articles.
There is also a difference between predicting what will happen, and what people would choose to do. The way the offseason has unfolded, it appears that AA has constructed the BP to feature Sanchez. Just because he seems destined to start in the back end of the pen, doesn't mean people are labeling him elite.
