This combine is going to be a pretty interesting one for this Defensive Back group because of how much uncertainty there is throughout the whole class. Jalen Ramsey is consistently highly ranked and Darian Thompson has picked up a lot of steam but after them, it seems like every defensive back at the top of the draft comes with a large set of questions.
Other than uncertainty at the top, there is also interest in this Safety class which could shape up to be one of the deepest safety classes in the past several years. Outside of Ramsey and Thompson, there are also names like Deon Bush, Keanu Neal, and Ohio States pair of safeties Von Bell and Tyvis Powell.
Jalen Ramsey
When you are doubted as a potential top-five pick, the Combine is obviously important. It could cement your status as a premier pick or your stock could plummet, depending on your performance.
Ramsey enters the draft with some track and field background. Ramsey won three All-ACC honors at FSU and starred in the long jump and the 4x100 relays. This type of explosion and overall athletic ability is evident on the field. He might not have great agility scores, bur expects his explosion numbers to be great.
Vernon Hargreaves
Hargreaves will either make the critics eat their words in Indianapolis, or he will prove them right. There is little in-between in his case.
Touted as an elite corner prospect throughout his college career, Hargreaves had a tough season in 2015 that led to more and more question his spot at the top of the draft. Currently, Hargreaves faces questions about his size and overall athletic ability.
Hargreaves is likely to be a loser during the measurements portion of the combine, but he can put himself right back into top 10 selection talk if he performs well in several drills, notably the 40-yard dash as he had an issue of getting beat deep at Florida.
Mackensie Alexander
Alexander, like Hargreaves, lacks the prototypical size of most Corners who are picked highly. He can also make up for this to a degree but having a good showing at the combine.
Alexander had a solid 2015 season but his size is a real issue. As is the fact that he didn't record a single interception in his entire college career. Alexander has a lot of talent but it will be hard to go to bat for a poor athletic tester who is also less than preferable size and has poor college production
Keanu Neal
The former Florida safety has had a lot more buzz around his name as of late as more and more people are catching up to watching him. There isn't really a better time to start getting noticed than before the combine, as now Neal will have more and more eyes focused on his performance.
It is important for Neal to have a good showing in Indy if he hopes to have his buzz continue towards the draft. If he tests poorly, then he will likely gain the tag of a player simply gained buzz because of the nature of the draft buzz.
Harlan Miller
There seems to always be one small school defensive back that puts himself on the map during the draft process. This year, it looks like the former Southeastern Louisiana player is this year's option.
Miller is reported to have had a good showing throughout the duration of the Senior Bowl week, and as a result, he was named the event's best defensive back. Now that Miller has the attention of those around the league, he can further propel himself up draft boards by showing out in Indy.
