Don't be surprised if the phones at the NFL Draft are ringing off the hook during the the first round on April 28.

Not only are the Titans interested in possibly trading the No. 1 overall pick, but another top-3 team could be looking to dump their pick, too: The San Diego Chargers.

According to the San Diego Union-Tribune, the Chargers are more than willing to listen to trade offers for the No. 3 overall pick. This is definitely good news for any team out there that needs a quarterback, but doesn't currently have the ammo to trade up to No. 1 to take the Titans' pick.

It's not cheap to trade up in the draft -- just ask the Redskins, who traded up to the No. 2 pick in 2012 -- so teams might be more willing to call the Chargers about the No. 3 pick than they would be for the Titans at No. 1. 

A trade would potentially be a smart move for the Chargers because the draft figures to be deep with defensive linemen, one position they sorely need. If San Diego trades down, there will still be plenty of talented linemen to choose from.

The Chargers don't pick in the top 10 often, but when they do, they have a history of wheeling and dealing. Back in 2001, San Diego held the No. 1 overall going into the draft, but ultimately decided to trade it to the Falcons. The Falcons took Michael Vick at No. 1, but the Chargers also came out happy because they got their quarterback -- Drew Brees -- with the first pick of the second round. 

San Diego also got LaDainian Tomlinson with the No. 5 overall pick in that same draft. 

In 2004, the Chargers landed the top pick again, which led to a huge trade with the Giants. San Diego selected Eli Manning with the No. 1 overall pick and then traded him to New York for several picks. Thanks to the Manning trade, the Chargers came away with Philip Rivers, Nate Kaeding (third round, 2004) and Shawn Merriman (first round, 2005). 

The last time the Chargers held on to a top-10 pick came in 2002, when they selected Quentin Jammer at fifth overall.
