Takeaway No. 4: 49ers do have a bit of a cornerback concern
Not all of what San Francisco has left us over four games is good.
If there's one major area of concern, it might be at cornerback. Sure, the right side of the offensive line has been iffy, but the prolific nature of the 49ers offense helps make up for it. It's been on defense, rather, where some of the bigger liabilities reside.
Primarily with the No. 2 cornerbacking spot opposite Charvarius Ward.
The Niners have played around with Deommodore Lenoir and Ambry Thomas in this spot, depending largely on who's the healthiest, but neither has exactly done enough to solidify the starting job this season. And opposing teams are beginning to realize this is probably the biggest defensive weakness San Francisco has right now.
Case in point, Lenoir has been targeted a team-high 30 times and has given up another team-high in yards with 201.
It might be a small weakness, but it's a weakness nonetheless.
