With the 49ers being half way through the 2013 season, quite a few rookies have played and the team has gone through some changes via free agency. While it is too early to make judgement on a rookie's future impact through eight games, there can be some evaluation done in this time frame.
Here are the grades for the 49ers draft picks and free agent signings through the first half of the season:
49ers 2013 Draft Picks:
S Eric Reid: A
In a class that was loaded with safeties which included two other players selected in the first round at that position, Reid has excelled as the team's free safety. He started out training camp behind Craig Dahl initially, but earned his playing time by now allowing anything thrown his way and keeping opponents in front of him.
Reid has lived up to the hype of replacing Dashon Goldson and is tied for the team leader in interceptions with three. He will only get better as time goes on, but he has impressed throughout the first half.
DT Tank Carradine: N/A
Carradine was added to the 53-man roster earlier this week. After suffering a torn ACL last year, he is ready to go and is expected to be a key pass rusher on the defensive line.
TE Vance McDonald: B-
McDonald has been used sparingly in the passing game as the team's No. 2 tight end behind Vernon Davis. He is intended to replace Delanie Walker for the long term and the rookie tight end has been successful as a blocker. McDonald can be seen as a run blocker and as an extra lead blocker when the 49ers use the full house pistol formation.
OLB Corey Lemonier: B
Lemonier has been used in a rotation with Dan Skuta when replacing the suspended Aldon Smith for five games. As a part time pass rusher, Lemonier looks to be a solid pick in providing extra depth at OLB, something the team lacked in 2012.
WR Quinton Patton: C-
Patton initially showed promise in the preseason after spending most of training camp with an injured hand. Unfortunately he only has one reception in his NFL career as he went down with a fractured foot in Week 4. When healthy, the 49ers used him sparingly in the passing game and had a limited number of snaps. Due to Patton not earning enough playing time, he has warranted a grade by playing in four games.
RB Marcus Lattimore: Excused
Lattimore was drafted for the longterm of the 49ers future backfield. He is not expected to take the field in 2013 after suffering two torn ligaments from a game in college back in 2012. There is some definite optimism for Lattimore going beyond the 2013 season as he could get practice time this year before heading to the injured reserve.
DT Quinton Dial: N/A
Dial has appeared in two games, but the 49ers are very confident in him going forward as he became part of the 53-man roster when he was eligible to come off the non-football injury list. He has received a limited number of snaps, but as a DT he has disrupted a few plays and showed flashes of promise. It's too early to mark a grade with Dial playing in two games thus far.
LB Nick Moody: N/A
Moody had a good training camp where he made tackles on special teams. Unfortuantely, he broke his hand in Week 1 and was placed on the injured reserve/designated for return list. The rookie linebacker practiced for the first time last week and is eligible to come off soon.
Note: Seventh round picks B.J. Daniels and Marcus Cooper are no longer with the organization while Carter Bykowski is a practice squad member. Cooper, in particular has stood out with the Kansas City Chiefs and has excelled at the nickel cornerback position.
49ers Free Agent Additions:
Kassim Osgood: B+
Osgood had a productive training camp before being part of the final cuts to the 53-man roster. He was added back to the team later in the season and has remained productive on special teams. Osgood has one touchdown from a muffed punt.
NT Glenn Dorsey: A-
Dorsey had to become the starting nose tackle when Ian Williams went down in Week 2. He has been an effective NT while playing an estimated 1/3rd of the team's defensive snaps. Dorsey has two sacks and 15 tackles, serving as a plug for the interior defensive line.
OLB Dan Skuta: A-
Dan Skuta has been one of the most underrated free agent signings by the 49ers this past offseason. After expecting to be a special teams contributor, the veteran LB became the starting OLB when Aldon Smith was indefinitely suspended. He has done well in both coverage and as a run stopper while Lemonier has the pass rushing duties. Skuta also had a 47-yard fumble recovery return for a touchdown.
S Craig Dahl: B
Dahl was brought in to compete for the free safety position which he eventually lost to Eric Reid. He has still been productive on the field as a special teams player even though he isn't at safety. Dahl has eight tackles on special teams so far this year.
S Ray "Bubba" Ventrone: A-
Ventrone made the team after impressing the coaching staff with his abilities on special teams. The veteran journeyman has been a decent tackler for kickoff coverage units and he serves as an extra blocker for Andy Lee on punts.
CB Nnamdi Asomugha: D+
Asomugha had a decent training camp showing his adequate press coverage abilities, but he struggled in tackling if he allowed a reception. After being injured in Week 3 against the Colts, Tramaine Brock has stepped in and not relinquished his job ever since. It would not be surprising if Asomugha is cut and Eric Wright is activated to the 53-man roster in his place.
K Phil Dawson: A-
He has made nine of out 12 attempts and two of the misses were in Week 4 against the St. Louis Rams. One kick was a 53-yard attempt and the other was a 71-yard free kick where there is forgiveness. The 38-year old veteran kicker has been reliable when needed and has converted ever PAT.
CB Darryl Morris: B+
Morris was promoted from the practice squad to the active roster in Week 4 in place of Aldon Smith. He has upped his value on special teams with his speed as a gunner and on the kickoff coverage unit. He was responsible for Osgood's touchdown against the Tennessee Titans in Week 7 when he got down the field to disrupt Darius Raynaud.
LS Kevin McDermott: A
McDermott beat out longtime veteran Brian Jennings as part of the final roster cuts. Jennings became a cap casualty as McDermott's cap hit is 1/3rd of what the 14-year veteran would have made. The undrafted rookie out of UCLA has been consistent on PATs, field goals and punts when called upon.
