The NFL Combine is a great chance for players to show exactly what they're made of, and there will be plenty of drills that scouts and coaches will be paying close attention to as the NFL's future stars take the field this week at Lucas Oil Stadium.
For some, the opportunity will be huge chance to take advantage of. For others, draft stock could drop by simply having an off day. Let's take a look at those athletes who have the most to lose heading into the big event.
5. Josh Rosen
Let's say Josh Rosen shows up to the combine and absolutely kills it. In that respect, it would be a loss for him since he has already hinted that he would not want to play for a rebuilding team like the Cleveland Browns. Rosen is regarded as the most NFL-ready prospect in the 2018 quarterback class. He's going into this event as the lead dog with all the other hungry quarterbacks looking to beat him. The competition will be high, and he'll have some serious pressure having to showcase and live up to all the offseason hype.
4. Calvin Ridley
The combine is meant to signal out the strengths and weaknesses of a player's game by putting them into drills that purposely make them feel uncomfortable. The wide receiver gauntlet is one of those drills, and those who usually excel are those who typically have the strongest natural athletic ability.
Calvin Ridley is no doubt a special talent with exceptional size, speed and route running ability, but those around question whether he has the best hands in the draft. Known to drop the easy ones from time to time and depend a little too heavy on body catches, he'll be forced to rely on those hands if he wants to rise above the rest of the wide receiver class.
3. Saquon Barkley
Saquon Barkley is the best player in this draft, hands down. He has the most versatility of any athlete, and will most likely get picked within the top five whether he showed up to the combine or not. But the grinder Barkley is, he has committed to participating in ALL drills.
There's no reason to do that when the game tape speaks so much louder than anything positive he could and likely will do at Indianapolis this week. No matter what, even if he has a bad day, it likely won't effect his draft stock, but why risk it when teams are already at an all-time high on him?
2. Sam Darnold
Like Rosen, Sam Darnold is also considered an NFL-ready prospect, so the rest of the invitees will be looking up and competing to top him. One thing about Darnold, though, is that despite being a phenomenal player, his delivery isn't exactly textbook. His arm motion and windup are both elongated by NFL standards, and he tends to dip the ball below his waist before coming around to the point of his release.
It's something that will be a mark against him assuming he hasn't began the process of correcting that minor flaw. Darnold's game thrives on his ability as a leader commanding 10 other guys on the field and improvising mid-play. That's something he won't get much of an opportunity to showcase in this setting.
1. Josh Allen
Josh Allen is the biggest anomaly heading into the draft. He literally has all the measurables with a 6-5, 235-pound frame and a cannon attached to the right side of his body. His accuracy, however, is spotty at best.
The problem with Allen is that he tends to struggle with his timing, and when he's behind, he typically rushes his throw, firing the ball as hard as he can to compensate. That often leads to sloppy mechanics where his elbow doesn't clear his shoulder and the ball either sails high or he grips too tight and looses its tight spiral.
He'll be throwing to a variety of different receivers who come in different shapes, sizes and speed, so he could struggle trying to establish any consistency throughout as the timing gets tougher and tougher to peg down.
