SAN FRANCISCO -- Grades for the 49ers' performance in Sunday's 24-24 tie against the St. Louis Rams:

<b>Quarterbacks: B </b>Alex Smith completed 7 of 8 before getting hurt. Colin Kaepernick was solid in relief, making up a 7-point deficit.

<b>Running Backs: A </b>No problem with Frank Gore, who rushed for 97 yards on 21 carries.

<b>Receivers: C </b>Michael Crabtree (5 catches, 70 yards) thrived with Smith, but didn't connect as well with Kaepernick.

<b>Offensive Line: C </b>The two QBs were sacked five times.

<b>Defensive Line: C </b>Not the dominant game you might have expected from Justin Smith and company.

<b>Linebackers: B </b>NaVorro Bowman (13 tackles) and Aldon Smith (2 sacks) definitely had an impact.

<b>Defensive Backs: D </b>Tough day for CBs Carlos Rogers and Chris Culliver, both tormented by Rams' Danny Amendola.

<b>Special Teams: D </b>Darcel McBath's fumble recovery on a kickoff was big; yielding 2 first downs on fake punts is unforgivable.

<b>Coaching/Overall: D </b>The 49ers showed their grit by climbing back in the game, but the Rams are a team they should beat.
