The 49ers surprised more than a few folks with their first picks of the Trent Baalke-Jim Harbaugh regime the past two years.

And in the lead-up to Thursday's first round, if you ask 10 people who they expect to see the 49ers select at No. 31, you might receive 10 different answers.

It's anybody's guess at this point, so let's make some guesses . . .

DL Cornellius "Tank" Carradine (Florida State): His teammate, Bjoern Werner, is a very good player. But Carrdadine is on a different level. He's got very good pass-rush moves off either side. He is a hard worker with a tremendous motor. He falls in this draft because he is coming off a torn ACL. It's difficult to imagine that he would fall to No. 31, so would the 49ers might have to move up to get him. He could fit in immediately as a pass-rush specialist to rotate in on nickel situations, giving much-needed breaks to Ahmad Brooks and Aldon Smith.

DL Margus Hunt (SMU): This former track star from Estonia has tremendous natural pass-rush skills. In many ways, 49ers defensive line coach Jim Tomsula would be working with a blank canvas. Hunt could be eased into the action on the defensive line to rest starters Ray McDonald and Justin Smith. Hunt can play 3-4 end, like McDonald and Smith, and then line up as an inside pass-rusher in the 49ers' nickel defense. Hunt (6 foot 8) could also prove to be a big special-teams player, as he showed with 17 blocked kicks in his career.
