49ers undrafted free agent tracker: DiAndre Campbell, DeAndrew White make it eight signings

The San Francisco 49ers agreed to terms with six undrafted free agents Saturday evening, and it appears they have found a seventh player. Matt Maiocco is reporting the team agreed to terms with Washington wide receiver DiAndre Campbell. The addition of Campbell means their UDFA class appears as follows (I've only pulled out the overlook from each NFL.com scouting report):

QB Dylan Thompson, South Carolina

NFL.com scouting report: One-year starter in the SEC with adequate size. Poor footwork and substantial accuracy and ball placement issues have him tabbed as a draft reject on several draft boards, according to scouts.

OLB Marcus Rush, Michigan State

CBSSports scouting report: Rush has tweener size and his lack of ideal length shows once engaged, struggling to shed blocks and keep himself clean ... average athlete at best, but plays like the energizer bunny ... doesn't have much experience dropping. Rush likes to mix it up off the edge with several secondary rush moves in his back pocket, throwing the kitchen sink out there in order to confuse blockers and keep them thinking ... rel[ies] on hustle to get the job done, which works in the Big Ten, but that probably won't be the case in the NFL.

WR Dres Anderson, Utah

NFL.com scouting report: Must work on becoming a reliable pass-catcher since he doesn't have the explosive traits for teams to overlook inconsistent hands. Anderson flashes great play speed when the ball is in the air and has the intangibles to become a good backup with low-end starting potential.

OL Patrick Miller, Auburn

NFL.com scouting report: Miller's long arms and rangy frame provide room for mass and might cause some initial intrigue, but his lack of functional core strength could make him an automatic reject for teams. Without greater play strength, Miller might have a difficult time trying to achieve his dream of playing in the NFL.

WR Issac Blakeney, Duke

Maiocco comments: He has the ability to put on some weight and also convert to tight end. The 49ers have eight tight ends, so he's likely to stay at wide receiver

WR Darius Davis, Henderson State

NFL.com scouting report: Davis needs to lose weight and prove to teams in a private workout that he can run in the 4.5s in the 40. While his level of competition didn't challenge him as often as you would like, the tape does show enough talent to warrant a trip into camp.

WR DiAndre Campbell, Washington

Attended 49ers local Pro Day. Caught career high 24 passes for 231 yards in 2014. 3 career touchdowns.

WR DeAndrew White, Alabama

NFL.com scouting report: High school speedster who appears to have lost a step since his 2012 knee injury, but who is still quick enough and athletic enough to find the open spaces and make yards after the catch. While his injury history could very well be a draft deterrent, White's talent should get him a look and give him a shot to make a team. He might have to return kicks to prove his worth early on.

Following the Phillip Wheeler signing, three releases and ten draft pick additions, the roster was at 81 players. The 49ers addition of seven UDFAs will put the roster at 88 players. I have to think the 49ers add another quarterback before training camp, and more than likely before they get to their OTAs. I would bet a lot of money they do not go into training camp with only three quarterbacks.

It is interesting that the 49ers are adding four wide receivers to the mix. They need some bodies for the offseason, and it will be interesting to see if anybody emerges for the practice squad or the 53-man roster.

Fooch's update: I just added DeAndrew White, who makes it eight UDFAs, giving the team 89 total players right now.
