NFL mock draft 2015: Who should we go with for the SB Nation mock draft?

The 2015 SB Nation mock draft has officially gotten underway, and our pick for the San Francisco 49ers is due. We have gotten through 14 picks behind the scenes, and announced the first three. I wanted to open up a thread for discussion to get your thoughts on who the 49ers should select in the SB Nation mock draft.

You can follow the entire mock draft HERE. The first three announced picks are as follows:

1. Tampa Bay Buccaneers - QB Jameis Winston
2. Tennessee Titans - QB Marcus Mariota
3. Jacksonville Jaguars - DE Vic Beasley

Here are the next 11 picks, in alphabetical order so as to not reveal the teams.

OT La'el Collins
WR Amari Cooper
OLB Dante Fowler
DE/OLB Randy Gregory
RB Todd Gurley
WR DeVante Parker
OT Brandon Scherff
DT Danny Shelton
CB Trae Waynes
WR Kevin White
DT Leonard Williams

With these picks in mind, let me know who you think I should select with the 49ers pick at No. 15. I don't have a poll yet, but will likely add one either late tonight or tomorrow morning. Who would you pick here?
