The NFL draft begins Thursday night with the first round, continues Friday night with the second and third rounds, and runs through Saturday, when the final four rounds will be held at Radio City Music Hall. The Indianapolis Colts and St. Louis Rams both went 2-14 last season and had the top two picks, but the Rams traded the second spot to Washington.

Some things to look for in this year’s draft:

AT THE TOP

The first two picks will be quarterbacks: Andrew Luck of Stanford, who will go to the Colts, followed by Heisman Trophy winner Robert Griffin III of Baylor, who is headed to the Redskins.

Luck is considered the most NFL-ready quarterback since Peyton Manning left Tennessee in 1998 for the Colts. Oddly, he will wind up as Manning’s replacement in Indy after the four-time MVP was released by the Colts and signed with Denver. Rarely do college quarterbacks call their own plays or have total freedom behind center. Luck did.

RGIII is more of a running threat than Luck and has a stronger arm. He did not play in a prostyle offense the way Luck did in college, but Griffin’s skill set and intelligence make him just as attractive as Luck.

A CRIMSON FIRST ROUND

From national champions to first-round draft picks.

Five members of the Alabama Crimson Tide could have their names called Thursday night at Radio City Music Hall, four from the outstanding defense.

Safety Mark Barron and linebackers Dont’a Hightower and Courtney Upshaw, cornerback Dre Kirkpatrick and running back Trent Richardson all are highly touted. Richardson is expected to go in the first six picks.

“We want to help them develop as a football player, which means have a great career here, win a championship and see if you can play at the next level,” Tide coach Nick Saban said.

Alabama has eight players likely to be drafted. The others are nose tackle Josh Chapman, cornerback DeQuan Menzie and wide receiver/kick returner Marquis Maze.

Roll Tide.

TOP JUNIORS

The first round will be packed with players who had eligibility remaining, including top choices Luck and Griffin. Richardson, LSU cornerback Morris Claiborne, Oklahoma State wide receiver Justin Blackmon and Mississippi State defensive tackle Fletcher Cox, all projected to go in top 10, are underclassmen.

A total of 65 underclassmen, the most ever, applied for the draft. Not all of them will get picked, but some will earn big bucks. Look for other non-seniors to go in the first round, such as Alabama’s Hightower and Kirkpatrick, linebackers Luke Kuechly of Boston College and Whitney Mercilus of Illinois, defensive linemen Nick Perry of Southern California and Michael Brockers of LSU, and guard David DeCastro of Stanford. ___

STRONGEST POSITION

Quarterbacks, running backs, receivers and defensive ends who pile up sacks are the glamour positions. They are not always the deepest positions in the draft.

This year, only three quarterbacks are expected to go in the opening round: Luck, Griffin and Ryan Tannehill of Texas A&M. The strength in this grab bag of a draft is at cornerback and on the defensive line.

It’s possible that four cornerbacks will come off the board in the first 32 picks, beginning with Claiborne. Others to watch for at that position are Stephon Gilmore of South Carolina, Kirkpatrick and Janoris Jackson of North Alabama. Crimson Tide safety Mark Barron is another defensive back almost certain to go early.

Defensive lineman likely destined to disappear in the first round are Perry, Brockers, Cox, Quinton Coples of North Carolina, Melvin Ingram of South Carolina, Kendell Reyes of Connecticut, Jerel Worthy of Michigan State, Devon Still of Penn State, and Upshaw, who can play linebacker or end.

SLEEPERS

Five players who could sneak into the first round: Dontari Poe, DT, Memphis; Kendall Wright, WR, Baylor; Cordy Glenn, OT-G, Georgia; Brandon Weeden, QB, Oklahoma State; Shea McClellin, LB, Boise State.
