I see Rapp more as a trade candidate

With Fuller coming off the serious ankle issue I think they will want to hold onto Rapp for depth. But, if Fuller is OK and Lake progresses at a reasonable pace I can definitely see Rapp traded (like Kenny Young a year ago) in October. They'd save around $1.3M tradng him midseason. And maybe they'd need that if, for example, they want to acquire an edge rusher before the trade deadline.
