The first wave of free agency is over and the 49ers will be shifting their focus toward the upcoming NFL draft as they try to make a run at the playoffs next season for the first time since 2013.

Kyle Shanahan and John Lynch had a strong first draft last spring, landing three starters on defense in the first three rounds (Solomon Thomas, Reuben Foster, Ahkello Witherspoon), a backup quarterback (C.J. Beathard), two important offensive weapons (George Kittle, Trent Taylor) and a starting-caliber defensive back and special teams ace in Round 7 (Adrian Colbert).

The team next month has nine more selections to work with, including pick No. 9 in the first round. San Francisco addressed holes in free agency, which could allow them to field 22 starters if they had to play a game next weekend. That means they can draft the best player available when they’re on the clock April 26.

Let’s take a look at three mock drafts published this week and break down how those picks would fit with the 49ers.

The Ringer: Roquan Smith, LB, Georgia

From Danny Kelly:

“Smith’s got the speed and the versatility to play three downs at multiple spots in defensive coordinator Robert Saleh’s 4-3 scheme. He could line up on the weak side next to Reuben Foster, assuming Foster gets back on the field in 2018—and if not, the team’s got a guy who can play in the middle as a run-and-chase playmaker like Bobby Wagner does in Seattle or Deion Jones does in Atlanta. In either case, he’s a sideline-to-sideline defender who could help change the complexion of the 49ers defense.”

Kelly is right on the money. Smith would give the 49ers a replacement for Foster if suspended for his two arrests this offseason – and Smith could line up next to Foster potentially forming the new generation’s NaVorro Bowman-and-Patrick Willis duo.

Veteran Malcolm Smith, who missed last season with a pectoral injury, doesn’t have any guaranteed money on his contract beyond 2018, meaning the 49ers should be in the market for his eventual replacement. Smith would be as strong a candidate as any and make give San Francisco’s defense another building block in the middle of the field.
