The lies and smokescreens and misdirection plays and paranoia will reach new heights between now and the April 30 NFL Draft.

The Serby 3.0 Mock Draft pushes Marcus Mariota up and out of reach of the Jets, and expands to include the first 20 picks. The Serby 4.0 Mock will go 25 deep before the final version on the eve of the draft takes a stab at the entire first round.

Jameis Winston
QB, Florida State

I’m leaving him here to land with coach Lovie Smith for now, but it ain’t over till it’s over, there are miles to go before the braintrust sleeps. If during the course of their investigation between now and the the draft, Smith and general manager Jason Licht discover more cause for pause, just one more skeleton in Famous Jameis’ infamous closet, then Marcus Mariota will be the pick. Can Winston, who looked and acted and sounded the part at the Combine, be trusted? Will he mature into the face of a franchise, more pro than con man? The Bucs are in this predicament in large part because they whiffed on Josh Freeman in 2009. They can’t afford to get this wrong.

Marcus Mariota
QB, Oregon

Sorry, but I don’t buy that coach Ken Whisenhunt is willing to rest his future on Zach Mettenberger’s shoulders. The questions about Mariota’s transition from a spread offense pale in comparison to whether Mettenberger can be the face of a downtrodden franchise.

Leonard Williams
DE/DT, USC

Richard Seymour was 6-foot-6, 299 pounds with 4.85 speed and the versatility to play up and down the defensive line when Bill Belichick and the Patriots made him the sixth pick of the 2001 draft. Jaguars coach Gus Bradley should welcome a 6-foot-5, 302-pound beast with 4.97 speed who can play inside and outside for his 3-4.

Amari Cooper
WR, Alabama

The Ghost of Al Davis is undoubtedly lobbying for Kevin White following his 4.35 40 at the Combine, but we’ll give QB Derek Carr the better route runner and safer choice.

Danny Shelton
NT, Washington

If Mariota falls, new GM Scot McCloughan, an elite talent evaluator, could be fielding trade offers. Barry Cofield was just cut. OLB Dante Fowler is an option to replace Brian Orakpo opposite Ryan Kerrigan, but OLB Trent Murphy mitigates the need to a degree. A true nose tackle, a 6-foot-2, 339-pound bully who treats running backs like rag dolls, enables coach Jay Gruden to better match up with the Cowboys’ offensive line.

Dante Fowler
OLB, Florida

NFL Network analyst Mike Mayock compares this 6-foot-3, 261-pounder to three-time Chiefs Pro Bowler Justin Houston, and last time I checked, Todd Bowles didn’t inherit anyone like that on the roster Rex Ryan and John Idzik left him. A pass rush is the best deodorant when your cornerback situation is a cesspool.

Shane Ray
DE/OLB, Missouri

Coach John Fox and defensive coordinator Vic Fangio need someone for their 3-4 to get in Aaron Rodgers’ face, and this is a relentless 6-foot-3, 245-pounder who has drawn comparisons to Jerry Hughes, Cliff Avril and Von Miller.

Randy Gregory
OLB, Nebraska

New coach Dan Quinn is desperate for a pass rusher, and though this kid carried just 236 pounds on his 6-foot-5 frame at the Combine, there are grits available anytime and any place in Atlanta, so he will be bulking up soon enough.

Brandom Scherff
G/T, Iowa

The rebuilding of coach Tom Coughlin’s offensive line — Justin Pugh, Weston Richburg, Scherff — is virtually completed with the addition of this year’s Zack Martin.

D.J. Humphries
T, Florida

White would be considered here, but something Jeff Fisher said following a December loss to the Cardinals resonates: “We need to be able to line up and say, `Here we come. This is what we’re running. Stop it.’ We’re not there yet.” Tackle Jake Long has a $10.5 million cap number and two ACL surgeries in two years and fellow tackle Joe Barksdale is an unrestricted free agent. And the fast-rising Humphries has the sweetest feet among the dancing bears.

Kevin White
WR, West Virginia

A 6-foot-3, big-play target for Teddy Bridgewater trumps the candidacy of CB Trae Waynes. White has been likened to Larry Fitzgerald.

DeVante Parker
WR, Louisville

A coveted 6-foot 3, 211-pound receiver with an 80-inch wingspan to replace Josh Gordon for Johnny Foot- … well, maybe not him. QB Josh McCown was just signed.

La’el Collins
G/T, LSU

Why the local over CB Trae Wayne or OLB Vic Beasley? Because the Saints are $23 million over the cap and may be forced to release guards Ben Grubbs and Jahri Evans, and RT Zach Strief turns 32 in September.

Trae Wayne
CB, Michigan State

Mike Tannenbaum & Co. pounce on the draft’s best corner with the size and speed (6-foot-1, 4.31) to bookend Brent Grimes — ironically in the same slot he traded up to for Darrelle Revis in 2007.

Vic Beasley
OLB, Clemson

If new defensive coordinator Eric Mangini gets his way, it will be because he will have convinced new head coach Jim Tomsula that this is not the second coming of Vernon Gholston, and because Ahmad Brooks will be a cap casualty and replaced by Aaron Lynch.

Jalen Collins
CB, LSU

When you play against Andrew Luck twice a year, you better replace free agent Kareem Jackson, and Collins is a 6-foot-1 corner with 4.48 speed. All that practice covering Odell Beckham Jr. will pay dividends.

Malcolm Brown
NT, Texas

The Bolts need a 6-foot-2, 320-pounder to shore up the 29th-best run defense.

Ereck Flowers
T/G, Miami

QB Alex Smith won’t last unless coach Andy Reid gets him better bodyguards. Flowers’ 37 reps at the Combine topped all offensive linemen.

Andrus Peat
T, Stanford

The TBD QB sure could use a bookend opposite Joe Thomas.

Arik Armstead
DE, Oregon

This supposes that coach Chip Kelly lands CB Byron Maxwell in free agency, and can’t help himself because this was one of his former Duck recruits.
