While Peter King of Sports Illustrated thinks the Titans might be content to keep the pick and Mariota for themselves, there are multiple teams that could make a serious trade offer for the No. 2 pick.
According to Conor Orr and Ian Rapoport of NFL.com, the Philadelphia Eagles aren't one of those teams. While a three-team trade involving the Eagles, Titans and Cleveland Browns that would involve multiple picks and players has been tossed around as a possibility, there are few more likely trade scenarios involving the second pick in the draft.
Orr cites three teams as the most likely trade partners for the Titans.
A year removed from taking Johnny Manziel in the first round of the 2014 NFL Draft, the Browns still aren't satisfied with their level of quarterback play. Trading up 10 picks from the No. 12 selection to acquire the second one is a big jump, but Cleveland is helped plenty by the fact that it owns the first-round pick of the Buffalo Bills thanks to a trade in the 2014 NFL Draft which landed Sammy Watkins in Buffalo.
Mike Florio of Pro Football Talk reported earlier in April that the Browns are seriously interested in packaging their pair of first-round picks together to move up and nab Mariota.
The fact that the Browns don't have a top-flight passer to send to the Titans hurts their chances of successfully brokering a deal, though.

The idea of teams packaging first-round picks together to move up is discussed whenever there is a team that manages to secure an extra pick. The reality is that those trades rarely come to fruition, though. If the Titans traded with the Browns, they'd snag another first-round pick, but is a drop of 10 picks really worth it if the team isn't on the receiving end of a quarterback of their own?
A trade involving the Charges seems entirely dependent on the team's situation with Philip Rivers. Trading the veteran quarterback is a move that actually makes a lot of sense for San Diego, but is a risky proposition considering the team would be dealing a known commodity away for a complete unknown in Mariota.
Still, if the Chargers don't make a deal involving Rivers now, it's possible they lose him in free agency eventually anyway, whether that's in 2016 or 2017 after the franchise tag is used. Cashing in that value now could be the team's best move.
While the trade rumors haven't disappeared, both Orr and King think that a deal involving Rivers won't happen, which would essentially kill any possibility of San Diego trading with the Titans.

There simply isn't much precedent for teams trading away franchise quarterbacks still playing at an elite level. Joe Montana was traded to the Kansas City Chiefs in 1993, but that was long past his prime, and deals involving Carson Palmer and Jay Cutler aren't quite at the same level as Rivers, who garnered MVP chatter in the first half of the 2014 season. The more likely scenario is that the Chargers hang on to their quarterback and the No. 17 pick.
The Rams already acquired a quarterback in the offseason when the team received Nick Foles from the Philadelphia Eagles. However, that deal sent away former No. 1 pick Sam Bradford, who was the more valued quarterback of the two in the trade and netted the Rams a few more draft chips to work with.
While Foles made the Pro Bowl in 2013, there doesn't seem to be much faith that he's the quarterback of the future for the Rams and the team has done thorough research on the quarterbacks in the 2015 Draft class, including Mariota.
Jeff Fisher has spent much of his coaching career working with mobile quarterbacks like Steve McNair and Vince Young, so a player like Mariota could end up better serving his offense than Foles.
Likelihood of Rams trading with Titans for Mariota: 1/10
The Browns have two first-round picks to work with and the Chargers have a franchise quarterback to dangle in front of the Titans. The Rams have neither, so mustering up the compensation necessary to jump eight spots from No. 10 to No. 2 could be way too pricy for St. Louis.
