Everybody has their own ranking positionally on draft picks after the top 2 guys. I've seen Donovan Ezeiruaku ranked as the 8th overall pass rusher and him as the 50th overall draft prospect and that's with 16.5 sacks.
He's only 6'2" and 265-270lbs with 32" arms. He'll struggle against the run and keeping the big olineman off his body. Ravens should use him as a situational pass rusher until he gets stronger or his technique against the run is refined, whichever comes first.
I just hate to see them overreaching on draft picks because I haven't seen Ezeiruaku ranked anywhere as a 1st round pick. If he can get them double digit sacks and force fumbles, he only caused 1 in college, not good, but can be coached to produce more, I won't care about him being a one trick pony.
