49ers fill their biggest need in this 1st-round mock NFL Draft

The Philadelphia Eagles started strong last year, but the horrific secondary caught up with them and the season ended with a whimper more than anything else. Philly needs multiple upgrades within the secondary.

Kool-Aid McKinstry entered the season with some serious hype as a potential top-10 selection, but that cooled a bit as his play didn't quite reach the heights it needed to.

He should still, however, be a first-round pick at some point in the draft.

McKinstry had seven passes defended but no interceptions for 2023. He didn't play badly, but not as well as people thought he would. His height is slightly short, but otherwise fine at 5-foot-11 and 199 pounds, and he's a fluid athlete, a good run defender and strong press corner.

There's some concern over his speed and whether or not faster receivers can give him the slip, and he might be better as a zone corner. The other question is whether he can be a boundary corner or needs to move to the nickel.

Brian Thomas Jr. isn't on the same level as the top receivers in this draft, but the Chargers would be delighted to get him as part of the Chargers-Vikings trade in this mock. Thomas Jr. should be the fourth receiver off the board and it isn't out of the question he gets picked in the top 20.

Thomas Jr. is an exciting blend of size and speed. He can be a mismatch at 6-foot-3 and 209 pounds but is also a vertical threat who was a touchdown machine for LSU. Additionally, Thomas Jr. had 68 receptions for 1,177 yards and 17 touchdowns in 2023, demonstrating his scoring ability.

The receiver isn't the finished product, however. He's good at routes that utilize his straight-line speed but struggles on the routes that require him to cut and use his hips to gain separation. He can struggle when pressed by corners also, which will need to be coached out.

There's room for him to grow, however, and the Chargers will definitely find a spot for him on the field early in 2024.

Tyron Smith is gone and Tyler Smith will permanently be the left tackle, so the Dallas Cowboys will need to look at a new right tackle as they look to capture the NFC and finally get to the Super Bowl in 2024.

Tyler Guyton would be an upgrade on Terence Steele, and can also play guard if Dallas wants to stick with Steele for now.

Guyton is a big guy with left tackle potential at 6-foot-8 and 322 pounds. He's a mauler who possesses significant athleticism, and he's a smart blocker who can use his footwork to mitigate pass-rushers.

Where Guyton is a question mark is some of his technique. He sometimes leaves his chest open in contests, which can allow stronger pass-rushers to take advantage, and whether or not he can be a left tackle or not is still up in the air.

In a strong tackle class, however, Guyton has some impressive credentials and can start right away for a team that will need him too.
