The Eagles, who are coming off a 4-12 season, have a lot of needs in the upcoming NFL draft.

They could use a quarterback who’s best suited to run the system of new coach Chip Kelly. They could also use an offensive lineman, perhaps an entirely new defensive backfield, and a rushing outside linebacker.

That’s why this year’s NFL Scouting Combine, which begins today and runs through Tuesday, is especially important for the Eagles. This is where they’ll interview prospective draftees and test them in every imaginable way — athletically, medically, mentally — in order to gauge their readiness to play in the NFL.

In all, 332 players have been invited to participate in the annual evaluationwa-fest. The Eagles have the fourth overall pick in the draft, which will be held from April 25-27. It’s their highest pick since quarterback Donovan McNabb was the No. 2 pick in 1999.

“I think we probably have better depth than we’ve had in the last 10 years,” NFL Network Draft Analyst Mike Mayock said during a recent conference call.

That’s not necessarily a good thing for the Eagles. Most draft experts don’t have a franchise quarterback at No. 4, let alone the top 20, unlike last season when quarterbacks Andrew Luck and Robert Griffin III went 1-2.

“The top 10 picks, I don’t see the difference makers like we’ve had the last several years,” Mayock said. “That’s why I wouldn’t want a top 10 pick this year. I think the fifth pick in the draft and the 25th pick in this draft are very similar.”
