John Simon, DE (Ohio State): Simon was a bit of a surprise for most fans, expecting an offensive tackle or wide receiver at this spot, after picking three straight defensive players to open the draft's first three rounds. He is 6'1", 257 pounds and probably translates more to an outside linebacker, situational pass rusher and special teams player.
Here is NFL.com's 'Bottom Line' assessment:
This two-time All-Big Ten pick and two-time Buckeyes captain lacks the height and length most NFL teams want in a defensive end, but teams with less stringent size requirements will covet his exceptional weight-room work ethic. He's late off the ball, and not an explosive athlete, but he understands pad level and hand usage. He's going to have to prove to teams that he can handle himself effectively enough in coverage.
Kyle Juszczyk, FB (Harvard): No one expected the Ravens to take a fullback in the draft, but perhaps salary cap issues may spell the end of Vonta Leach's time in Baltimore. Juszczyk is 6'1" and 248 pounds. Not much is known about him other than he appears to be a beast to bring down and is a better than average pass receiver.
Here is his overview from NFL.com:
At Harvard's pro day, ran the 40-yard dash in 4.72 and 4.71 seconds. He had a 37-inch vertical jump and a 10-foot-1 broad jump. He ran the short shuttle in 4.19 seconds and the three-cone drill in 6.93 seconds. He performed 24 lifts of 225 pounds on the bench press. Juszczyk played some tight end and H-back for the Crimson, but worked out at fullback at his pro day.
