Yes, in this mock draft, the 49ers do execute a trade down from the No. 31 overall pick, again making a move with the Chicago Bears.
It’s done on the assumption the Bears want to move on from quarterback Mitchell Trubisky, who hasn’t exactly lived up to the expectation level Chicago had when it previously moved up with the Niners to No. 2 overall in the 2017 NFL Draft with San Francisco to get him.
The Bears also don’t have a first-round pick at their disposal. So if they want to cash in on one of the first-round quarterbacks likely to go, a trade up with the Niners is feasible.
In this scenario, it costs both of Chicago’s second-round picks: No. 43 overall (from the Las Vegas Raiders) and its own, No. 50 overall.
Now armed with two Round 2 selections, the 49ers restock their questionable wide receiver corps, which could lose Emmanuel Sanders to free agency this offseason.
TCU wideout Jalen Reagor already met with San Francisco at the NFL Combine. And while Reagor’s combine workouts were impressive enough, he was largely overshadowed by other receivers, such as Alabama’s Henry Ruggs III and his blazing-fast 4.27 40-yard dash.
Still, Reagor is a good enough consolation prize, and it wouldn’t be shocking at all to see him slip into the middle stages of the second round now.
By adding him, the Niners help solve some of their question marks at the position and can now focus on other key needs.
