Here’s how the 49ers stack up with the Rams position by position:
QUARTERBACKS: 49ers. The Rams have terrible quarterbacks.
RUNNING BACKS: 49ers. Zac Stacy is a promising young running back, but he averaged just 3.9 yards per carry last season, and he has no one proven behind him.
WIDE RECEIVERS: 49ers. San Francisco has three established receivers — Anquan Boldin, Michael Crabtree and Stevie Johnson. The Rams have zero established receivers.
TIGHT ENDS: 49ers. Jared Cook can’t block, and neither can Lance Kendricks.
OFFENSIVE LINE: 49ers. Scott Wells is a good center, and Greg Robinson may become a dominant tackle one day. But Joe Staley is better than Jake Long right now, Mike Iupati is better than Brandon Washington, and Alex Boone is better than Roger Saffold.
BASE DEFENSIVE LINE: 49ers. The Rams don’t have a dominant run stopper on their base D-line.
NICKEL DEFENSIVE LINE: Rams. St. Louis has one of the best Nickel D-lines in the NFL. Robert Quinn had 19 sacks last season and Chris Long had 10. The Rams drafted DT Aaron Donald in Round 1, and he had 11 sacks last season at the University of Pittsburgh.
LINEBACKERS: 49ers. Even without NaVorro Bowman, the 49ers have better linebackers than the Rams. Patrick Willis still is an excellent all-around defender, and Ahmad Brooks is one of the 49ers’ best run-stoppers.
CORNERBACKS: 49ers. Trumaine Johnson played well last season. He allowed just 523 yards in 892 snaps, and a 74.5 passer rating. But Janoris Jenkins was awful. He gave up seven touchdowns and a 115.3 passer rating last season.
SAFETIES: 49ers. Eric Reid was a Pro Bowler last season. The Rams don’t have any Pro Bowl safeties.
SPECIAL TEAMS: Rams. The 49ers and Rams both have excellent punters and kickers. But Tavon Austin is a bigger weapon as a punt returner than LaMichael James.
