The best case scenario for the 49ers in the 201

9 NFL draft is one where quarterback Kyler Murray goes first overall. San Francisco opens the door to select the top edge in the draft – Ohio State's Nick Bosa. The typical way this has happened in mock drafts is the Cardinals taking Murray with the top pick. An alternative scenario plays out in the latest Draft Wire mock that would rock the entire league.

A blockbuster trade with the Raiders and Cardinals moves the Raiders up to the No. 1 overall pick from No. 4. Arizona acquires Nos. 27 and 35 to move down three spots. Oakland then takes Murray, allowing Bosa to drop to the 49ers.

It's not out of the question that San Francisco trades back from No. 2, but it feels inevitable that Bosa picks up the event Murray goes first

Here's how the four-round mock draft shakes out for the 49ers:

He's big, fast, strong, and technically sound after years of working with his NFL star brother, Joey. There's no way Bosa can do that as an edge defender. Adding him to the side opposite Dee Ford is the 49ers' pass rush from one of the league's worst to one of its best. Being great at getting to the quarterback is almost as important as having a great quarterback.
