The Redskins’ fifth overall draft selection may suddenly be worth much more following the NFL scouting combine.

Tampa Bay clearly looks like it will take Florida State quarterback Jameis Winston with the first overall selection on April 30, leaving Oregon quarterback Marcus Mariota as the only other prominent passer. If Mariota’s available at No. 5, he would become major trade bait.

Picking ahead of Washington is Tennessee, Jacksonville and Oakland. Those teams aren’t looking for a quarterback and could also trade down, but each seems more likely to draft a top-tier player to build around.

Tennessee may draft USC defensive lineman Leonard Williams second overall. At No. 3, Jacksonville could take Nebraska pass rusher Randy Gregory, even though he’s undersized.

Oakland is the most likely team ahead of Washington to trade its pick. But the Raiders covet fast receivers and West Virginia’s Kevin White ran a 4.35 in the 40 at the combine. White’s speed could make him the No. 4 pick over Alabama receiver Amari Cooper.

The Raiders were suckered by Maryland receiver Darrius Heyward-Bey, who was chosen seventh overall in 2009 after posting a 4.3 in the 40. The problem was Heyward-Bey was a track star rather than a football player, so he’s now on his third NFL team.

If Oakland goes receiver again, then Washington would have four potential trade partners for Mariota in the New York Jets (sixth), St. Louis (10th), Cleveland (12th) and Philadelphia (20th). However, there are problems trading with each of those teams.

The Jets aren’t giving up much to flip one draft spot with the Redskins — unless there’s another suitor wanting Washington’s pick. Can the Redskins fake interest from others? Thus begins two months of football’s version of liar’s poker.

St. Louis would be the natural trade partner. Washington could fall to 10th and get Alabama strong safety Landon Collins and a second-rounder. But Redskins owner Dan Snyder surely will want the Rams to overpay for the No. 5 pick as some sort of payback for Washington’s costly 2012 deal for quarterback Robert Griffin III. Watch Snyder’s greed kill that trade, and St. Louis land Iowa offensive tackle Brandon Scherff at No. 10.

Is Cleveland ready to give up on 2014 first-rounder Johnny Manziel and go for Mariota? Good question, and a good one to debate over the next two months. Washington could still get a starter with the 12th pick, plus it would get several lower picks in the deal.

A trade with Philadelphia seems unlikely. Why would Washington help an NFC East rival gain a needed passer? The Redskins would be better off keeping the fifth pick than trading with the Eagles.

Washington has lots of needs so trading for more draft picks seems likely, especially if Mariota’s the bait. It’s just a matter of finding the right trade partner. And if not, maybe Washington will take Mariota with the most mind-blowing pick of the entire draft.
