2. Isaac Seumalo instantly becomes the best part of Steelers OL

Becoming the best offensive lineman on the Pittsburgh Steelers used to mean something. Nowadays, it's not an impossible bar to clear. While Isaac Seumalo has yet to play a snap in black and gold, I feel very confident that he will be the best offensive lineman Pittsburgh has in 2023.

The biggest reason is that there just aren't any holes in his game. While James Daniels is a fantastic pass protector, he's not a mauler in the running game. Seumalo can do both. Last year, he graded out as the 10th-best offensive guard in the NFL, according to Pro Football Focus.

Listed at 6'4'' and 303 pounds, Seumalo is on the small side for a guard, but don't let that fool you. The former third-round pick doesn't lack power and is as well-balanced as they come. Previously on a loaded Eagles offensive line, Seumalo is often overlooked, but he will soon show why he deserves more credit.

Injuries have been an issue in the past but managed to say healthy for the entire 2022 season and was one of the best in the business. He will slide in as a starter (probably at left guard) and prove to be a significant upgrade over Kevin Dotson.
