It's always exciting when an NFL team selects a playmaker in the first round of the draft. Fans get an exciting glimpse of the quarterback who shows the potential to lead the franchise to the big dance, the wide receiver whose game-breaking speed will propel the offense to new heights or the running back who can control the pace of games with his punishing running style.

We received a peek at the best players those positions have to offer during Saturday's workouts at the scouting combine.

Before the combine, the only way to evaluate these prospects was watching as much of their available college tape as possible. Now, we have a better idea of what they all bring to the table after getting an up-close look at their technique and recorded measurements of their speed, agility and strength. Rest assured, big boards are already being altered.

So, which of these players impressed enough to work their way toward the top of mock drafts? Here's an updated look at the first round following the combine's Day 4 action.

Analyzing Notable Day 4 Performances

During Saturday's workouts, some prospects put forth great efforts and will be highly rewarded once the draft rolls around. Most of these performers were already shoo-ins to be selected in the draft's first round, but many may hear their names called sooner than originally anticipated.

Here's a look at a handful of prospects who really stood out on Saturday and where they are likely to land on April 30.

1. Tampa Bay Buccaneers: Jameis Winston, QB, Florida State

There were whispers regarding the Buccaneers favoring Jameis Winston leading up to the scouting combine. Well, the Florida State product certainly helped his case to go No. 1 overall during Saturday's workouts. He may not have dazzled with his 40-yard dash time of 4.97 seconds, but he excelled in practically every other drill.

Winston wasn't flustered under the bright lights at Lucas Oil Stadium, appearing confident and throwing crisp, well-placed balls. He displayed great velocity on some passes, nice touch on others and a very accurate deep ball. Sure, there are still questions about his character, but Winston absolutely performed like a prospect worthy of No. 1 overall consideration on Saturday.

2. Tennessee Titans: Marcus Mariota, QB, Oregon

The Titans' draft decision just became more difficult. The team needs help along the defensive line, and there is a great prospect ripe for the picking in Leonard Williams. However, selecting a quarterback with game-changing ability is certainly alluring. Marcus Mariota showed he is exactly that on Saturday.

The Oregon product recorded the fastest time of all quarterbacks in the 40-yard dash, running a solid 4.52 seconds. A big concern for Mariota was his ability to make the required NFL throws after spending time in a non-traditional offense with the Ducks. He showed a good throwing motion, nice accuracy, a good deep ball and consistency during Day 4 drills. He may be too difficult to pass up at No. 2 overall.

4. Oakland Raiders: Kevin White, WR, West Virginia

Kevin White may be the biggest freak in the draft. At 6'3" and 215 pounds, he was still able to run the 40-yard dash in a blazing 4.35 seconds. Daniel Jeremiah of NFL Media tweeted his praise for the receiver soon after the run:

Kevin White posted a silly time but trust me, the tape is even better.

Not only is White quick, but he showcased his strength on Friday night, posting 23 reps on the bench press. Adding to his spectacular showing, White was extremely fluid in positional drills, running a clean gauntlet and displaying a great blend of fluidity, acceleration and soft hands. That's the combination that will make him the first wide receiver selected this year.

10. St. Louis Rams: Amari Cooper, WR, Alabama

Amari Cooper may not have put up gaudy workout numbers like White, but he did exactly what was expected of him. A 40-yard dash time of 4.42 seconds is nothing to sneeze at, and he displayed a good mix of acceleration and top-end speed. However, where he really flourished was in positional drills.

Cooper was already known to be a very polished prospect, running crisp routes and making tough catches look easy. He proved why he was routinely analyzed that way on Saturday. Here's what Bleacher Report's Matt Bowen had to say:

Matt Bowen @MattBowen41

Any question on Amari Cooper as a Top 10 pick? Speed, clean routes + SEC production.

The Rams have a solid receiving corps, but adding Cooper to the mix would give the team a true No. 1 option for years to come.

31. Seattle Seahawks: Sammie Coates, WR, Auburn

David J. Phillip/Associated Press

Auburn wide receiver Sammie Coates was expected to be one of the combine's workout warriors, and he proved to be exactly that on Saturday. He ran a solid 4.43-second 40-yard dash and was a top performer in the bench press, vertical jump and broad jump. While that was all good, one of his biggest knocks haunted him during positional drills, via College Football 24/7:

CollegeFootball 24/7 @NFLDraft

Sammie Coates just had a drop on a deep ball. Mayock: "That's the knock on him right there."

Aside from some drops, Coates ran a nice gauntlet, looking very agile in the process. His size (6'1" and 212 pounds), speed, power and athleticism can't be coached, but his reliability as a receiver can. Taking him late in the first round and developing his skill set will be very intriguing for teams in need of a wide receiver.
