Exactly. Every year, on every team, there are bubble guys, who live on the edge of the roster, they get waived, put on the PS, waived to be put onto the active roster, get called up & put on to the active roster, and back again through this cycle. Chris Harris did it his first year, Shelby Harris will likely grab a starting spot this year here, & may have a solid backup spot now, but was a bubble guy before on other teams. Fowler was a bubble guy, so was Heuerman (his injuries played a role), both have solid roster spots now, unless they pull a Norwood & screw up. Todd Davis, before he got to start was inactive, active, waived, etc. It's just life for guys who are at the end of the roster.
