Oh yes, of course Eaton would need to prove himself this year. Everything I have read seems to indicate he is putting in the time and effort to impress. Obviously he is liked by the Colts since they drafted him and if they still like him and Rivers gives us 2 years, he would be the obvious QB to slide in to the starting spot. If Reich and Ballard don't see the potential in Eaton I suppose they will draft or sign another QB.
Practice squad, right?
