NFL Combine Results 2015: Day 5 Highlights, Twitter Reaction and Recap

The 2015 NFL Scouting Combine heated up on Day 5. Between the skill positions running 40-yard dashes and the top quarterbacks airing it out alone, Saturday's action from Lucas Oil Stadium was worth watching.

One of the biggest storylines ahead of the draft is the battle to be the first quarterback chosen. Florida State's Jameis Winston and Oregon's Marcus Mariota are the two competitors, and one could go to the Tampa Bay Buccaneers with the top overall pick.

While Mariota showed off his far superior speed in the 40-yard dash, smoking Winston's best of 4.97 seconds with a blazing 4.52 (unofficial), Winston appeared to be best in throwing drills.

Even though the QBs were throwing against air, there was little question that Winston refortified the notion that he's the best pocket passer in the 2015 class. It may have been enough to give him an edge over Mariota.

Bleacher Report's Matt Bowen was impressed with Winston's skills:

CBS Cleveland’s Daryl Ruiter expressed the same sentiment, though, he did cite Winston's off-field issues that linger as perpetual red flags:

Mariota's blend of size and athletic ability led to a gaudy comparison put forth by NFL Network:

There are similarities to Mariota and Green Bay superstar Aaron Rodgers in their mobility, arm talent and quick release. What remains to be seen is whether Mariota can pick up a pro-style offense quickly after being in a spread, QB-friendly college system.

Below are some of the best moments from Mariota's day in Indy:

As charismatic and mild-mannered as Mariota is, with an apparent aptitude for picking up offensive concepts, NFL Network's Albert Breer relayed information about Winston:

All other signal-callers are jockeying for position to be the third QB chosen, and UCLA's Brett Hundley made a strong case on Saturday.

Josh Norris of Rotoworld observed just how quickly Hundley ran after a stellar 4.63-second unofficial 40:

"

Not only is Brett Hundley's 20 yd SS the best for QBs since 2006, it is the 2nd best for RBs since 2006. His 3.98 just behind Rainey's 3.93

ESPN's John Clayton applauded the job Baylor product Bryce Petty did in challenging the assertion that Hundley is the third-best quarterback:

This piece of information from ESPN's Adam Schefter regarding Hundley and the Cleveland Browns, owners of two first-round picks for the second year in a row, is most interesting:

While Hundley and Petty did their best to be No. 3 at their position, the trio of wideouts atop most big boards lived up to the hype. Bleacher Report expert Matt Miller hinted at that in his analysis:

West Virginia's Kevin White did the most to help his stock. Despite coming from a spread system in Morgantown, there is no denying White has serious ball skills to go with rare speed that he showed off at Lucas Oil Stadium.

Daniel Jeremiah of NFL Network didn't seem too shocked by the buzz surrounding White after his 4.35-second 40-yard dash:

FoxSports.com's Peter Schrager logged a quote from White prior to Saturday's workouts—words that take on serious meaning now that his blend of size and explosiveness is officially known:

Eric Edholm of Yahoo Sports weighed in on Louisville star DeVante Parker's fast and furious trail to the finish in the same 40-yard drill:

ESPN Stats & Info tweeted a graphic that might be a good omen for Alabama Biletnikoff Award winner Amari Cooper:

To touch on one more wideout in the first-round conversation: Arizona State's Jaelen Strong.

ESPN draft guru Todd McShay weighed in on how Strong's combine performance aided what his game tape showed:

Georgia wideout Chris Conley and UAB product J.J. Nelson provided some eye-popping numbers, which had to have helped their respective stocks on Saturday:

Running backs aren't as appreciated in the NFL today. There hasn't been a first-round draft pick since 2012.

Wisconsin's Melvin Gordon has a chance to change that this year. However, he was upstaged by a couple of his peers in what could have been his defining moment to make himself a lock for the top 32.

As ESPN's Louis Riddick points out, though, it's dangerous to judge someone based off one drill, and Gordon's 40 time wasn't catastrophic:

Michigan State's Jeremy Langford wowed with his 40 time, comparing well to the NFL's most recent champion rusher:

Another backfield prospect who may have flown under the radar is Northern Iowa's David Johnson. He was among the top performers in the 40 (4.5 seconds), got up 25 repetitions of 225 pounds on the bench press and had a 41.5" vertical, per Jeremiah.

The NFL Scouting Combine not only shows what players can do up close in drills, but it also nurtures the climate for inside information to leak out from interviews. This creates all sorts of speculation about draft stocks and can have a huge impact on mock scenarios and big boards.

But Saturday's flashier positions went a long way in confirming what was suspected of many of the top prospects in action. Winston seems to be the best pro-style QB, the three-receiver race heated up and the running backs showed solid if not transcendent ability as part of a deep class.

Outliers like Nelson won't have helped themselves as much as someone like White, whose 40 time went well above expectations. White and Strong could be argued as some of the biggest winners from Saturday's slate.

Months remain until the first round starts on April 30. The combine results once again promise to make the pre-draft season as hotly debated and exciting as ever.
