Possibly. We do tend to sign free agents now who are easily cutable if they don't prove worth keeping or a young player outplays them. Unfortunately, those free agents also tend to be players who are easy to outplay.
In looking at them, I do like that Inman was able to put up solid second-receiver numbers in 2016. Of course, he did that because injuries led to him playing 90 percent of the Chargers' offensive snaps that year, so it had a lot to do with opportunity. The Chargers traded him the next season for a seventh-round pick, so clearly they weren't that impressed.
