NFL Draft 2017: 1st-Round Mock Draft and Buzz After Scouting Combine Day 4

The 2017 NFL Scouting Combine's impact won't stop creating ripples right until the draft itself.

A sometimes ho-hum affair in Indianapolis was anything but this year through the first four days. Usually it confirms what scouts have already seen on tape and teams get the all-important medical evaluations out of the way.

Not this year. In nothing short of a great development, a handful of players with soaring stock have made the NFL realm pause and go back to watch more film, pairing the workout numbers with what's on the screen to come up with an adjusted grade and overarching stock market.

Some prospects have disappointed, of course. Showing up among the best of the best and struggling is much more common than a prospect blowing away scouts and sending them back to the film room.

Through four days, mock drafts have changed in dramatic fashion thanks to a few key performances. Let's take a look at an updated mock and some of the key movers generating buzz.

Buzz After Scouting Combine Day 4

Stock Up: Christian McCaffrey, RB, Stanford

Going into the combine, Stanford running back Christian McCaffrey seemed like a nice change-of-pace option in the pros who could come off the board near the end of the first round.

McCaffrey wasn't having any of that talk.

Measuring in at 5'11" and 202 pounds, he ripped off a 4.48 40-yard dash, hit on a vertical of 37.5 inches and busted out a three-cone drill of 6.57 seconds. All of a sudden, 1,603 rushing yards and 13 touchdowns in 2016 and another 2,019 rushing yards in 2015 made more sense.

For context, here's NFL on ESPN:

For historical context, NFL Research pointed out that only one back has completed the three-cone drill faster since 2003.

In other words, this wasn't a back who feasted on bad competition or a numbers-inflating scheme. McCaffrey really is that good, even if his size won't technically allow him to be an every-down back.

But that's the beauty of the draft and today's NFL—McCaffrey in today's passing league is a nightmare for NFL defenses. A team able to get the ball to him in space will help him tally outstanding numbers while opening things up for the offense.

In the above scenario, the Indianapolis Colts see McCaffrey's huge day, pair it with Dalvin Cook's miserable showing and pull the trigger. He's a versatile weapon for Andrew Luck to lean on in any situation.

Stock Down: DeShone Kizer, QB, Notre Dame

The muddy situation at quarterback seemed destined to sort itself out a bit in Indianapolis.

Notre Dame's DeShone Kizer, though, didn't plan on helping out the process by struggling with the basics absent pressure.

Kizer, a huge-upside prospect who struggled thanks to a 4-8 team around him last year, looked like a top-10 pick. Weighing in at 6'4" and 233 pounds with a booming arm and ability to throw well on the run (not to mention bowl over defenders) had his stock in a holding pattern until he lined up next to his fellow quarterback prospects.

Without anyone pressuring him while working through the paces during drills, Kizer looked erratic at times, misplacing the ball and seeming hesitant. CBS Sports' Rob Rang described a few instances:

The issues went beyond on-field performance, too, as Bleacher Report's Brent Sobleski detailed:

A bad combine isn't the end of the world for a guy like Kizer. He's always carried "project" status, but struggling with confidence on a major stage is an eyebrow-raising development. His looking erratic without defenders on the field suggests sometimes-erratic film isn't totally explained by a poor Notre Dame team around him.

As such, Kizer dips in the above mock, landing with the Arizona Cardinals, a team willing to work with him and let him develop for a few years.

Stock Up: John Ross, WR, Washington

Yes, Washington's John Ross smashed Chris Johnson's combine record in the 40-yard dash, blazing a 4.22 time.

And yes, it was as impressive as it sounds:

No, Ross didn't win himself an island because he laced up in Nike cleats. Too bad.

What Ross did do, though, was solidify his status as a first-round pick. The 40-yard dash isn't the best indicator of NFL success by any means, but it was one part of an overall impressive performance—he also posted a 133-inch broad jump.

These numbers are impressive on their own, but what bumps Ross' stock the most is the fact he's doing this after a string of collegiate injuries. He checked out in the evaluations portion of the draft before going on to make history in drills.

At 5'11" and 188 pounds, Ross' 24 touchdowns on all of 134 touches makes sense. He's an NFL-ready talent who can return kicks and stretch defenses out of the slot, a set of traits amplified by an iffy wideout class.

In the above scenario, the Philadelphia Eagles are the perfect fit. The team needs better weapons surrounding Carson Wentz, and Ross is the typical mold similar to a DeSean Jackson or Brandin Cooks.

Provided nothing medical comes up in the near future, Ross will remain the biggest winner of the combine process.
