DETROIT – Over the past week, the Detroit Lions draft needs have changed a little bit.

The team brought in Golden Tate to be the No. 2 receiver and re-signed Brandon Pettigrew as the team's tight end. While the signings don't mean those needs have evaporated for Detroit – the Lions need receivers still and could use a stretch-the-field tight end – it made both of those spots less important to draft in the first round.

It also gives Detroit some flexibility, as does not have to draft a quarterback.

The Lions would potentially consider trading up in May's draft or dropping back from the No. 10 slot in the first round. Team president Tom Lewand and general manager Martin Mayhew recognize that every option needs to be available.

"It always sounds good on paper to trade up or trade back. The old adage is it takes two to tango and sometimes opportunities present themselves for trades on draft day or outside of draft day and sometimes they don't," Lewand said Monday night at the MGM Grand in Detroit. "Our position is we always have to be ready to improve our team in whatever way is possible.

"Sometimes we search those things out and they don't materialize and sometimes they are presented to us and we take advantage of them. We have to be ready, no matter what the opportunity is, if there's a chance to improve the defense by trading up or trading back, we'll look at that and if it makes sense, we'll do it."

May's draft offers some intriguing opportunities there. But who would be worth the Lions making a move from No. 10 -- either up or back -- for? That depends somewhat on how the draft falls and somewhat how the Lions final board ends up being set up.

This also focuses mostly on defense.

WORTH MOVING UP:

Sammy Watkins, WR, Clemson: Watkins is the top receiver in the draft and the only offensive player that would be worth making a move higher into the Top 10 for, although even then, it would be questionable how much Detroit should be willing to give up for him. Watkins is a special talent, but having grabbed Tate in free agency, that alleviated receiver from being the No. 1 need. But if Watkins ends up still on the board at No. 8, it might be worth exploring jumping over Buffalo to ensure Detroit grabs him.

Jadeveon Clowney, DE, South Carolina: Just putting him here in case the inexplicable happens and he drops beyond the third or fourth pick. If he does, the Lions should trade whatever possible to go and select him. But it would be very, very, very unlikely to happen.

Khalil Mack, LB, Buffalo: Mack may be the best non-Clowney defensive prospect in the draft and for a little while, it appeared he might end up falling to No. 10. If he did, Mack would almost be a no-brainer selection for Detroit as long as Watkins was no longer available. If Detroit determines Mack is the best player in the draft, it could be worth investigating a move higher for a linebacker that could end up being an All-Pro.

STAY PUT IF THIS PLAYER IS HERE:

Anthony Barr, LB, UCLA: The Lions are clearly intrigued by Barr, who has extreme athleticism and could improve a good but not great linebacker group immediately. Mayhew was out at his Pro Day to watch him perform. His speed/size/frame combination makes him extremely intriguing.

Mike Evans, WR, Texas A&M/Eric Ebron, TE, North Carolina: They are both options for Detroit at this spot, but both positions are deep in this draft and are no longer massively pressing needs due to the signings at the top. But if Mayhew and Lewand wanted to go offense, these would be two likely targets.

IF THIS IS THE TARGET, TRADE DOWN AND TAKE A CHANCE:

There are teams below Detroit with needs and other than the defensive backfield, there is not a major pressing need for the Lions in the first round. So the Lions could make a smart play depending who is available and who is interested and try to trade down to stockpile picks in a deep draft. These four potential targets could merit a trade down.

Ha Ha Clinton-Dix, S, Alabama: He has already come in for a visit with the Lions and is one of the top safeties in the draft. He is rated as the No. 16 overall player and has long, rangy arms. He'll almost definitely be available at No. 10, but if the Lions covet him, they could probably drop down a few places and still nab him.

Calvin Pryor, S, Louisville: Similar situation to Clinton-Dix. He's a little bit shorter than his Alabama counterpart at 5-foot-11, but he was listed as 6-foot-2 in college. He's rated one spot ahead of Clinton-Dix as the No. 15 overall player and should be available at No. 10, too. For either safety, Detroit could probably trade down as low as No. 14 or No. 15 and still be able to take either player.

Justin Gilbert, CB, Oklahoma State/Darqueze Dennard, CB, Michigan State: The top two cornerbacks in the draft are both of first round value and should almost definitely be available when Detroit is picking. If the team decides corner is the area they want to go in the first round, they could drop a couple of places and select one of these players.

IF PICKING TODAY, I'D TAKE:

Barr. Offense may be sexy, but the Lions need to focus on and improve their defense from back to front. They have two strong running backs, two dynamic wide receivers and can add in the draft. But to find an impact starter in the first round, Detroit would benefit from going defense with its first pick and Barr could be the best available.
