I recently published a new page called NFL Disaster Ratings where I discuss how dire each injury, retirement and suspension is for each team. I included Anthony Davis as one of the write-ups. The right tackle surprisingly retired, so he'll need to be replaced.

Vernon Davis won't be on the 49ers much longer, and former second-rounder Vance McDonald hasn't shown any signs that he's worthy of taking over as the starter.
San Francisco signed Torrey Smith, but the organization could use a young replacement for Anquan Boldin as well.
Treadwell (6-2, 229) had 48 receptions for 632 yards and five touchdowns in 2014 before an ugly knee injury ended his season. He is a natural receiver who causes a lot of mismatches. Treadwell was one of the top recruits in the nation, and as a freshman, he was immediately effective against SEC defensive backs. Treadwell caught 72 receptions for 608 yards with five scores in 2013.
Pick change; previously Taylor Decker, OT

The 49ers could have taken cornerback help early in the 2015 NFL Draft, but curiously selected another safety. That could leave corner as a big weakness this coming season.
White has played well the past two seasons with two picks in each year and solid run support. He had 55 tackles as a freshman and 33 stops as a sophomore. White has shown steady ball skills while batting away seven passes in 2013 and six as a sophomore. White has the potential to take his game to another level and rise higher as a junior. White (5-11, 191) is fast with enough size and also is a dangerous punt returner.
