49ers final 7-round mock NFL Draft ahead of 2021 free agency

Round 7, Pick No. 238 Overall: 49ers select offensive tackle Adrian Ealy, Oklahoma

Even if the 49ers are able to re-sign Trent Williams in free agency, they’ll still have a need to bolster the depth behind him, and a developmental swing tackle would sure help matters.

A lot of this depends on the futures of reserve linemen like Shon Coleman, Justin Skule and Colton McKivitz. But with right tackle Mike McGlinchey’s long-term future also a question mark, it wouldn’t hurt to start exploring some contingency options now.

If anything, finding some competition to push the other depth pieces would do some good.

At 6-foot-7 and 326 pounds, Oklahoma offensive tackle Adrian Ealy still needs to add some functional strength to his long frame to be effective in run support and against stronger pass-rushers at the NFL level. The good news, though, is he hasn’t totally filled out yet. And his long limbs are already proving to be a boost to his pass-protecting efforts.

More of a zone-style blocker, Ealy needs some coaching to hone his technique, as he’s relatively easy to knock off balance because of his large and lankier build.

But he does have the long-term potential to be a decent swing-tackle reserve player within a year or two, and there’s the remote chance he could turn into a quality starter if put into the right situation.

The 2021 NFL Draft kicks off on Thursday, April 29.
