The injury bug has gotten to Keenan Allen twice in his career, causing him to miss significant time. This happens a lot within the Chargers roster, but when healthy Allen is a dynamic threat. He is another big time volume guy, seeing 100 or more targets in his healthier seasons. Playing with Philip Rivers gives him a bump, and Allen has been his go-to guy. If Allen can stay healthy, he has a promising second half to his career ahead of him. If not, Allen is going to go down as one of the bigger what if players in the league.
