Let’s take stock of the 49ers through the first week of free agency.But before we do, let’s acknowledge that free agency isn’t done and the 49ers almost certainly will add more players. This exercise merely is an attempt to a se s what the 49ers have accomplished so far.THE GAINSCornerback Charvarius WardWide receiver/return specialist Ray-Ray McCloudLinebacker/special teams specialist Oren BurksSafety/special teams specialist George OdumNose tackle Ha san RidgewayTHE LOSSESGuard Laken Tomlinson (New York Jets)Nose tackle D.J. Jones (Denver Broncos)Offensive tackle Tom Compton Brandon Lowe Jersey (Denver Broncos)Scroll to ContinueRunning back/special teams specialist Raheem Mostert (Miami Dolphins)Running back/special teams specialist Trenton Cannon (Tenne see Titans)Wide receiver/special teams Tyler Glasnow Jersey specialist Trent Sherfield (Miami Dolphins)THE GOODThe 49ers clearly improved at cornerback with the addition of Charvarius Ward, as he was one of the top cornerbacks on the market and he’s only 25-years old. Now, the 49ers have three starting-caliber outside cornerbacks in Ward, Emmanuel Moseley and Ambry Thomas, and depth is key for the 49ers, because Moseley mi ses lots of games.The 49ers also made three big additions to their special teams (McCloud, Burks and Odum), and they should offset the 49ers’ three big lo ses on Jake Smolinski Jersey special teams (Sherfield, Cannon and Mostert).THE NOT SO GOODD.J. Jones is a big lo s — he was by far the 49ers’ best interior run defender.And the offensive line is worse than it was a week ago. Laken Tomlinson is gone and the 49ers haven’t signed a replacement, which means they probably will sign a backup in a few weeks and have him compete with last year’s second round pick Aaron Banks, who didn’t play in 2021. He would be a big, big downgrade Matt Andriese Jersey from Tomlinson.The 49ers also lost right tackle Tom Compton, and most likely will replace him with another downgrade (Colton McKivitz?) unle s Mike McGlinchey makes a dramatic and speedy recovery from tearing his quadricep muscle off the bone. There’s no guarantee he ever will play again.You would think the 49ers would want to improve their offensive line to give Trey Lance the best chance po sible to succeed. Strange.Until the 49ers sign some starting-caliber offensive linemen, they haven’t improved their team. In fact, they’ve gotten slightly worse, although they’re still quite good.
