DETROIT -- We're less than two weeks away from the big thing, and although some of us will never be mock drafted out, I can't blame some of you for feeling that way.

So let's try something a little different. Rather than simply evaluate the mock selections national media made for the Lions at No. 21 overall, as I have just about every weekend of draft season so far, I want to do more of a pro-con list with these.

It's the good, the bad and the value.

Here's how this week's selections measure up:

Mike Williams, WR, Clemson

The good: With the Lions in need of a No. 1 receiver, a player who can bully in man coverage and a top red-zone threat, the 6-foot-4-inch, 218-pound Williams could be the playmaker general manager Bob Quinn has said he needs.

The bad: With mere 4.5-second 40-yard-dash speed at his pro day and a history of concentration drops, Williams has some of the same deficiencies that kept the Lions from finding big plays down the stretch last season.

The value: Williams has a chance to be the best player available at No. 21, but if the Lions believe in Marvin Jones as a No. 1 receiver, they can find a No. 3 later.

Alabama CB Marlon Humphrey

The good: With three Lions cornerbacks entering a contract year, the 6-foot, 197-pound Humphrey would bring the well-rounded athletic traits and top-level college experience to complete a talented duo with Darius Slay.

The bad: Teryl Austin's Cover-4 scheme is built all around preventing the deep pass, and playing the ball on those kind of long bombs was Humphrey's Achilles' Heel at times at Alabama.

The value: The Lions have a No. 1 cornerback and this position is as deep in any in this draft, so a pick here would probably need to truly be the best player available.

Kansas State DE Jordan Willis

The good: Willis had 21 sacks and 33 tackles for loss combined the past two seasons behind a tremendous motor, which is something the Lions could value off the edge after all the times Aaron Rodgers has killed them on scramble drills.

The bad: The 6-foot-4-inch, 255-pound Willis needs to grow both in his mass to defend the run and in his counter moves to better rush the pass, so he might not be an instant fix at the position.

The value: Defensive end is deep, but starters need to come in the early rounds. This currently feels like a reach based on where most places have Willis, but he does have great effort and posted a 4.53-second 40-yard-dash time that led all true defensive linemen at the NFL Scouting Combine, so it's possible.

Florida LB Jarrad Davis

Jarrad Davis, LB, Florida

Mocked by: NFL.com's Bucky Brooks

The good: The 6-foot-1-inch, 238-pounder was a productive run-stuffer at Florida and wowed at his pro day with a 40-yard dash time in the 4.6-second range and a vertical jump of 38.5, better than all but four defensive backs at the combine.

The bad: He missed five games with injuries last season, and his tackling might not be as ready as a team would like to start him from Day One.

The value: This draft has a few linebackers with demonstrated coverage abilities and then falls off. Although the Lions could wait and still find value, the size of their need at this position could urge an early move.

Missouri DE Charles Harris

The good: With a devastating first step, a sick spin move, quality athletic measurables and a high motor, Harris has a high floor as a pure pass rusher.

The bad: At 6 feet 3 inches and 253 pounds with bad habits in run defense, Harris will only be a pass rusher early and might not be an ideal fit for a Detroit front four that prefers larger ends.

The value: A deep defensive end class gives the Lions plenty of options with high ceilings, but finding a starter out of the first couple rounds will be difficult.

Miami TE David Njoku

David Njoku, TE, Miami

Mocked by: Bleacher Report's Matt Miller

The good: Just 20 years old and with eight red-zone touchdowns last season, the ceiling is high for a 6-foot-4, 246-pounder who could give the Lions some two-tight end mismatch sets with Eric Ebron next season.

The bad: Njoku is so young that he might not answer questions about Ebron's future in time or be pro-ready in time for the Lions to truly take advantage of having both on the field at the same time.

The value: This tight-end class is deep with receiving-only options to find in the middle to later rounds, so forcing another pick at this position would feel like a reach with all the needs the Lions have to fill.
