What do the 49ers do if Nick Bosa and Josh Allen are both gone?

The San Francisco 49ers improved to third in the 2019 NFL Draft order with their loss to the Chicago Bears on Sunday. They close out the season traveling to face the Los Angeles Rams, and odds are pretty good they’ll end up with a top five pick in the 2019 NFL Draft.

With the No. 1 pick likely out of reach, edge rusher Nick Bosa is likely no longer an option for the 49ers. That leaves edge rushers like Josh Allen and Clelin Ferrell and a cornerback like Greedy Williams among the top options. Others might consider N’Keal Harry or Rashan Gary, but edge rusher and cornerback would seem to top the list.

SB Nation’s Dan Kadar is back with his latest 2019 NFL mock draft, and he offered a tweak that would impact the 49ers. Last week, he had the Oakland Raiders selecting Alabama defensive tackle Quinnen Williams, but this week he had them selecting Josh Allen. That would take two edge rushers off the board right before the 49ers pick at No. 3.

Kadar did not include trades, and instead had the 49ers drafting Greedy Williams. He thinks a trade makes sense at the spot.

The 49ers will be in a bad spot if Bosa and Allen are gone. If that’s the case, they should trade down. Sure, Rashan Gary of Michigan is intriguing, but he’s far too similar to players San Francisco already has on the roster. Williams could be San Francisco’s long term fix in pass defense.

There will be trades within the top ten, but the big question will be where the quarterbacks fit into the mix. As Kadar pointed out, it’s a weird year for the position with nobody in the top five expected to be looking at the quarterback position. The Tampa Bay Buccaneers, Jacksonville Jaguars, New York Giants, Miami Dolphins, and Washington are all teams in the top half of the draft board that might look for the future at the position. Maybe we see one willing to climb all the way up to No. 3?

If the 49ers do not move down and were to grab Williams, what would you make of that? An edge rusher is critical, but adding a potential shutdown corner would be quite the consolation prize. The 49ers head into the offseason with Richard Sherman, Tarvarius Moore, and Ahkello Witherspoon competing for two starting spots. Would the 49ers invest a high pick in the position if they can’t land an edge rusher at No. 3?
