From Bill Barnwell over at Espn, doing a mock of trades. Every team had a trade, here is the link and here is what he said for us.
I would be ok with this, depending on who is available at 16. But coming away with all these picks would be huge.
49ers get: 1-16, 6-186 Ravens get: 2-34, 4-109, 4-143, 2018 second-round pick
If the 49ers aren't confident about getting Kirk Cousins and want to draft one of the defensive stars with the second overall pick, here's a deal in which they get back into the middle of the first round to nab a quarterback. The Ravens are likely looking for pass-rushers and offensive linemen, and in this draft, it's better to go after those guys in the middle rounds. Ozzie Newsome should be effective at drumming up interest in this pick from teams looking at quarterback options, and while it would be tempting for the Ravens to trade this selection for San Francisco's 2018 first-rounder, my deal provides a mix of useful draft assets for a Baltimore team that is increasingly dependent upon guys playing out rookie deals.
