There is no question that the biggest need the Titans have is an EDGE rusher. In case you have been under a rock, Derrick Morgan and Brian Orakpo are entering the final year of their respective deals. Both guys are nearing the end of their NFL careers, and even more than that, the Titans currently have zero depth behind them. Harold Landry is the dream pick at #25, but my bold (#notreally) prediction is that he will be gone when the Titans pick.
My guess is that the top EDGE guys left on the board when the Titans pick are Josh Sweat and Sam Hubbard.
