Campbell's relatively short arms (32 5/8 inches) and narrow frame (77 3/8-inch wingspan) may push him inside at the next level, but the 49ers are thrilled to see him available here to challenge for the open left guard spot. Like the Colts' Braden Smith and others, Campbell may eventually get the chance to prove himself outside to replace Trent Williams or Colton McKivitz.

The 49ers have been churning the roster quite a bit lately, and have a need at corner. Barron is CB2 (behind Travis Hunter) on most boards, and while I'm not as high on him as the majority, this is a pick that would make sense for both sides.

The 49ers start to rebuild and reinforce their roster with a pick in the trenches. Harmon is equally adept at defending the run and pass, and can be asked to fill a variety of roles along the interior. He would be great in the 49ers' heavy use of twists and stunts, and he gives San Francisco a young player to start replenishing its recently tenacious front.

Day 1 grade: B+
Day 2 grade: B-
Day 3 grade: B

Analysis: Pearsall's quickness and hands warranted first-round consideration, and the team needed a receiver with the potential trading away of Deebo Samuel or Brandon Aiyuk down the road. The 49ers could have also picked a cornerback or tackle at that spot. Green and Puni will contribute in areas of need, but trading up for Puni was a bit of a stretch. They did not re-sign Chase Young after sending a third to Washington at the deadline.

Mustapha, picked with the selection gained from Dallas for quarterback Trey Lance, should see time on defense and special teams as a rookie. The 49ers hope to get more from Guerendo than recent running back picks Trey Sermon and Tyrion Davis-Price. Cowing is small but crafty, and Kingston's guard/tackle versatility makes him a valuable backup.

Top needs entering the draft: Offensive tackle, cornerback, wide receiver

The 49ers' roster is solid from top to bottom, but I would have liked to see GM John Lynch bring in competition for right tackle Colton McKivitz, who allowed 11 sacks last season and also was a below-average run-blocker. That was San Francisco's biggest need in Round 1, in my eyes. Lynch went a different direction, reaching a little bit for Ricky Pearsall (31), my 10th-ranked wide receiver. Pearsall has great hands and will be an asset in the run game as a blocker, but there were better players available at the end of Round 1.

Then, the 49ers had the biggest reach of Round 2, selecting my No. 21 cornerback Renardo Green (64) about two rounds too high. That was a confusing one, as there were still some good corners on the board. I do like what Lynch & Co. did after that, though. Dominick Puni (86) has the potential to be a starting guard in time. Safety Malik Mustapha (124) is impressive in coverage and will be a dynamo on special teams. Running back Isaac Guerendo (129) ran a blazing 4.33-second 40-yard dash at the combine and averaged 6.1 yards per carry last season, though he had only one year of steady production. The 49ers traded Nos. 173 and 176 to get Gurerendo, so they must like him a lot.

Snagging Puni keeps the 49ers' grade out of C territory, though I do think Pearsall will be a good pro.
