The 49ers own the No. 31 overall pick in the 2020 NFL Draft, but they are extremely short on selections this year after that. 

San Francisco has just one pick in the top 150. After the first round, the 49ers won't be on the clock again until the fifth round. They own two fifth-round picks, one in the sixth and two in the seventh. 

Between the second and fifth rounds, it's completely barren for general manager John Lynch and coach Kyle Shanahan. But NBC Sports' Peter King looked at how San Francisco could accrue more selections this April

Here's what King wrote in his latest Football Morning in America column. 

To project the Niners’ path, I looked north for a clue. The arch-rival Seahawks, with ever-restless GM John Schneider, provided an excellent example in 2019 of how to turn one first-round pick into a bevy of picks, replenishing what would have been a thin crop.

The trades:

Seattle traded its first-round pick, 21st overall, to Green Bay for the 30th, 114th and 118th picks.
Seattle traded the 30th pick to the Giants for the 37th, 132nd and 142nd picks.
Seattle traded the 37th pick to Carolina for the 47th and 77th picks. At 47, Seattle picked S Marquise Blair.
Seattle traded the 77th and 118th picks to New England for the 64th pick. At 64, Seattle selected WR DK Metcalf.
Seattle traded the 114th pick to Minnesota for the 120th and 204th picks.
Seattle picked WR Gary Jennings Jr. at 120, S Ugo Amadi at 132, LB Ben Burr-Kiven at 142, and RB Travis Homer at 204.

 

So Seattle turned pick 21 into picks 47, 64, 120, 132, 142 and 204 ... two second-round picks, two fourth-round picks, one fifth-round pick and one sixth-round pick.

The 49ers lost their second-round pick when they acquired defensive end Dee Ford in a trade with the Kansas City Chiefs last offseason. They then lost their third- and fourth-round picks when they acquired wide receiver Emmanuel Sanders in a midseason trade with the Denver Broncos.

But they added a fifth-round pick in the Sanders trade and a seventh-round pick from the Detroit Lions in a 2018 trade where they shipped away linebacker Eli Harold.

The 49ers don't have too many holes on their roster after losing to the Chiefs in Super Bowl LIV. However, depth is always a must, as they learned this season. With Jimmie Ward being an unrestricted free agent, the 49ers could target a safety early in the draft. They also likely will have their eyes on a loaded receiver class and depth on the interior offensive line. 

To add picks, though, they might have to take a lesson from their biggest rivals.
