Interior players offer immediate upgrades

Teams picking early in the first round of the NFL draft need and expect the prospects they choose to contribute right away.

It's happening right now with quarterbacks like Andrew Luck, Robert Griffin III and Ryan Tannehill offering quick returns on investment, and defenders like Luke Kuechly and Morris Claiborne also have stood out as rookies in 2012.

Which players from the 2013 class could make the same kind of impact when they step on the field next season?

After I took a look at the top of our Scouts Inc. draft board, four players jumped out to me as the kind of plug-and-play prospects who will make an immediate difference. Plenty of players flash huge upside, but these four already have the skill sets to become successful pros.

There is no slam dunk quarterback prospect in this class, and the other skill positions are also a little thin up top, so the players below will all make their living mixing things up along the interior.
