The Panthers are an interesting team, not just in this draft but in their entire team-building strategy right now.
They are in a state of rebuild, and after inking their new signal-caller, they have several holes that need to be filled.
Assuming they take a guy like Isaiah Simmons with their first pick, the board could fall in such a way that a player at another major position of need could be available when the Titans are on the clock.
After losing Dontari Poe, Vernon Butler, and Gerald McCoy from their d-line, the Panthers are reportedly interested in TCU lineman Ross Blacklock. Blacklock is widely expected to be a late-round selection, and honestly, might even be a fit for the Titans. However, I believe the Titans would choose to add more picks instead of selecting a backup DT at 29.
The 49ers pick two selections after the Titans, and once again the Niners might be the reason a team feels compelled to switch spots with the Titans. After trading away DeForest Buckner, the Niners could have their eyes on a defensive lineman at the end of the first round.
Trading with the Titans makes sure the Panthers jump the Niners and get their guy, while Tennessee gets a good pick in the second round and a nice pick in the 3rd round for their trouble.
