The Redskins are looking for a new star, but identifying which one will fall to them is a challenge.

This is the most wide-open NFL draft in many years. The only sure thing Thursday night is Florida State quarterback Jameis Winston going first to Tampa Bay. After that, Tennessee could take Oregon quarterback Marcus Mariota or trade the second pick, but the passer likely won’t fall to No. 5, where the Redskins await.

The Jaguars are known for surprises, so selecting USC defensive end Leonard Williams at No. 3 seems too logical. Don’t be shocked to see them take Clemson linebacker Vic Beasley.

At No. 4, Oakland could go for Alabama receiver Amari Cooper or Williams, but when was the last time the Raiders didn’t go rogue? Florida linebacker Dante Fowler Jr. is another option for Oakland.

With the fifth pick, the Redskins will get a solid player, but which one? And trading down to get more picks might be their preference.

Despite exercising quarterback Robert Griffin III’s 2016 option, the Redskins could still take Mariota as insurance or future trade bait. If the Oregon passer somehow falls to No. 5, he won’t get by the Redskins.

Mariota dropping would be general manager Scot McCloughan’s dream, as the trade value of the No. 5 pick would increase. Washington has seven selections, but McCloughan said Monday he’d like to get 10 players in this draft so expect some trades.

If the Redskins were able to find a suitor for the No. 5 pick — and get something like a first- and second-rounder in return — Washington could take Iowa offensive lineman Brandon Scherff plus get a needed safety later in the draft.

If the Redskins keep their No. 5 pick, they’ll likely take a defensive pass rusher among Williams, Fowler and Beasley. McCloughan loves big players, so Fowler (261 pounds) is probably his top choice.

The Redskins need a big red zone receiver, so West Virginia’s Kevin White could also be an option.

The real long shot would be taking Washington nose tackle Danny Shelton, who’s massive inside.

It would take a numbers cruncher to decipher how the first five picks will unfold, but the likeliest order is Winston, Mariota, Williams, Beasley — with Fowler heading to Washington.
