John Lynch is taking no prisoners in his first NFL Draft as the general manager of the San Francisco 49ers. He began by trading the No. 2 pick, acquiring the No. 3 pick and a trio of additional selections. Lynch then used some of his draft capital to move back into Round 1.

The 49ers traded with the Seattle Seahawks to acquire the 31st overall pick in exchange for pick Nos. 34 (second round) and 111 (fourth round).

San Francisco used the selection on Alabama linebacker Reuben Foster. The prototype linebacker entered the draft as one of the top defensive prospects in his class. His stock fell some when news broke of a diluted drug test taken at the NFL Combine.

Even so, he's an elite talent that Mike Mayock had ranked as the No. 7 player on his big board.

"He reminds me of Luke Keuchly when I watch tape," Mayock said on NFL Network after the 49ers made the selection. "He's an immediate impact player."

Added his colleague Daniel Jeremiah: "If his shoulder is right, we're talking about the best pick in the draft."

Foster racked up 115 total tackles, 13 for loss and five sacks for the Crimson Tide in 2016. He's touted as a sideline-to-sideline linebacker who can excel both in stopping the run and in pass coverage. There's so much more to come on San Francisco's second first round pick. Stay tuned.
