Interior O-line options at No. 30

We're inside of two weeks until the first round of the NFL draft. Near the end of that day, the 49ers are scheduled to make a selection.It'll be repeatedly stated up to April 26 that the 49ers do not have to draft for need. But there are positions that appear to set up better than others for a selection at that point.We'll look at some of those positions in the next few days. Interior offensive line is one of those spots.Taking into account the obvious -- that Stanford guard David DeCastro -- will be long gone, here are four interior offensive lineman who could be available to join a competition with Daniel Kilgore and, perhaps, Alex Boone for the 49ers' starting job at right guard:C-G Peter Konz, Wisconsin
Ht: 6-5; Wt: 314
Bench press (225 pounds): 18
He could compete as a rookie for a starting job at guard while figuring in as the long-term answer at center. (Jonathan Goodwin is 33 and signed for another couple seasons.)G-T Kelechi Osemele, Iowa State
Ht: 6-5 12; Wt: 333
Bench press (225 pounds): 32
He has the athleticism and physical tools to be dominant, including an 86-inch wingspan.G Amini Silatolu, Midwestern State
Ht: 6-3 58: Wt: 311
Bench press (225 pounds): 28
He dominated at the NCAA Division II level as a left tackle. He'll be a guard in the NFL. His good feet and willingness to play to the whistle are attributes that make him worthy of a late-first or second-round pick.G Kevin Zeitler, Wisconsin
Ht: 6-3 78; Wt: 314
Bench press (225 pounds): 32
He earned the full-time starting role at right guard as a sophomore. Not a physical specimen, but is a dedicated worker who exhibits good technique and toughness.
