5 Offensive Standouts from the 2015 NFL Scouting Combine

As we begin to wrap up our coverage of the 2015 NFL Scouting Combine, let's take a look at a few prospects who shined in Indianapolis.

Attention-grabbing players like Florida State quarterback Jameis Winston and West Virginia wide receiver Kevin White were examples of guys who solidified their positions at the top of the draft.

Here are five additional prospects who raised their draft stock with strong showings at Lucas Oil Stadium.

1. Georgia WR Chris Conley

Viewed as a late-round prospect going into the combine, Conley's performance in two of the week's marquee events forced scouts to take notice.

The 6-foot-2, 213-pound wideout ran a 4.35-second 40-yard dash (fourth overall) and recorded a 45-inch vertical jump (first overall and tied the combine record).

As a senior last fall in Georgia's run-heavy offense, Conley hauled in 36 passes for 657 yards and eight scores while averaging 18.3 yards per catch.

Bonus: If the 49ers draft Conley – he's now considered a mid-round prospect – he could be a candidate to join the 49ers Studios production team.

2. Arizona State WR Jaelen Strong

A back-shoulder savant in college, Strong consistently made physical plays on the boundary to leap up and snatch away passes at their highest points.

But entering draft season, scouts had questions about Strong's vertical speed, wondering if he would be able to get separation in the NFL.

Strong responded at the combine by running a 4.44-second 40-yard dash, a fast number for a player of his size (6-foot-3, 217 pounds).

The wideout has been compared to Arizona Cardinals receiver Larry Fitzgerald, who posted a 4.63-second 40 time in 2004.

Strong also recorded a 42-inch vertical jump, which stood as the fifth-best overall and second-best among receivers.

NFL.com projects the Cleveland Browns to take Strong with the 19th overall pick.

3. Northern Iowa RB David Johnson

At 6-foot-1, 224 pounds, Johnson is built like downhill bruiser.

But throughout his workout at the combine, the tailback proved that he is plenty athletic as well. 

Johnson ranked in the top five at his position in the 40-yard dash (4.50 seconds), vertical jump (41.5 inches), broad jump (127 inches) and three-cone drill (6.82 seconds). Oh yeah, and he also put up 25 reps at the bench press, good enough for fourth by a running back.

Johnson's surprisingly quick 40 time was actually faster than Wisconsin running back Melvin Goldon, who ran a 4.52 despite being nine pounds lighter.

Then, in his positional drills, Johnson showcased what makes him even more unique – his seamless ability to come out of the backfield and make plays in the passing game.

Johnson, a three-time 1,000-yard rusher at Northern Iowa, finished last season with 38 receptions for 536 yards. His success as a dual-threat garnered a comparison to Chicago Bears running back Matt Forte.

Like Conley, Johnson is also projected to be taken on Day 2 of the draft.

4. LSU OT La'el Collins

There were questions heading into the combine about whether or not Collins could stay at the all-important left tackle position in the NFL. Some analysts thought he would be a better fit on the right side or even at guard due to a lack of athleticism.

But by running a 5.12-second 40-yard dash and showing swift feet in his positional drills, Collins may now be looked at by teams in need of blind-side protection.

Collins recently penned a draft diary piece for *USA Today, *saying that "Left tackle is definitely where I want to play in the NFL."

NFL.com projects the LSU product to go 13th overall to the New Orleans Saints.

5. Hobart College OL Ali Marpet

From the Division III school in New York, Marpet began his ascent by performing well at the Senior Bowl last month, where he reportedly held his own against projected top-10 pick Danny Shelton from Washington.

At the combine, Marpet turned in the fastest 40-yard dash time of any offensive linemen (4.98 seconds) and had the second-best time in the three-cone drill (7.33 seconds) and 20-yard shuttle (4.47 seconds).

Moreover, he put up 30 reps at the bench press to prove that he has strength to go along with quickness.

Listed at 6-foot-3, 307 pounds, Marpet is expected to be taken in the middle rounds of the draft. He would be the first Hobart alumni to play in the NFL since the 1930s.
