Draft days have become more stressful for the Baltimore Ravens because there has been less volatility.

The Ravens would traditionally see prospects ranked in their top 100 still available at the end of the draft. Not anymore. The irritating trend for Baltimore in recent drafts is watching its board get wiped clean.

"It just seems like everybody is using the same cheat sheets," Ravens assistant general manager Eric DeCosta said.

Parity in the NFL has extended into the draft, which has created more frustration for the Ravens. This has particularly been the case in the first round.

Baltimore had the top part of its draft board picked clean in 2010 and 2012, which led to the team trading out of the first round both years. The Ravens would've done so again in 2015 if wide receiver Breshad Perriman -- the lone remaining player ranked in their top 15 -- wasn't available at No. 26.

"Everybody is sort of drafting from the same players," DeCosta said. "There are not a lot of surprise players. They seem to be coming off in the same general area. It just seems like everybody is working off the same script way more than years past."

While there have been fewer surprise players, teams still go to great lengths to keep their targeted prospects a secret. Teams will bring in players for pre-draft visits whom they don't intend to draft to create subterfuge. When general managers talk at this time of year, it's more like a game of poker than a conversation.

"There is a lot of information out there, and I would say I am really close to probably 12 [or] 13 GMs. I have no clue what they are doing. I really don't," general manager Ozzie Newsome said. "Why would you tell someone what you are thinking about? Because if you are like me, then I will just jump you and get the player from you. There is a ton of information out there about who is going and what round and all of that, and to me, you just set your board and pick."

To set their board, the Ravens have long prided themselves on how they do all the legwork compiling information on players. Baltimore is one of five teams -- the Colts, Raiders, Redskins and Patriots are the others -- who aren't affiliated to the two major scouting services (BLESTO and National) that assist teams with the evaluation process.

As a result, the Ravens' draft board would be completely different than other teams. It used to be commonplace for the Ravens to chuckle at teams taking players Baltimore didn't like early in the draft. These days, Baltimore is often sweating out whether one of its coveted players will still be available when the team is on the clock.

Now there's just not much variation in each round. It has become increasingly more difficult to get any steals in the draft because of all the information available online and the proliferation of mock drafts.

"It never used to be like that," DeCosta said. "In the last few years, I have been amazed that when we look at our list of players, basically every player that we had ranked was drafted. It used to be different, quite a bit different."
