As of right now, the Titans only have four “reliable” receivers on the roster, and when I say “reliable,” I mean that to separate the top 4 (Rishard Matthews, Corey Davis, Taywan Taylor, and Tajae Sharpe) from the practice squad (Darius Jennings, Zach Pascal).
General Manager Jon Robinson is likely not finished adding free agents to this team, and there are still a few unsigned veterans with the potential to contribute (like Brice Butler and Jordan Matthews, to name a couple).
