Steelers under-the-radar signings that could have a huge impact in 2023

1. Cole Holcomb could be what Devin Bush was supposed to be

I want to be careful not to overhype a fifth-year linebacker with an injury history, but I am pleasantly optimistic about what Cole Holcomb will provide the Pittsburgh Steelers in 2023. Where Devin Bush was so passive at the 'Mack' linebacker position during his tenure with the team, Holcomb will not be.

Instead of leaning back on his heels and allowing the play to come to him, Holcomb is going to dart to the ball carrier. His aggressive demeanor and sideline-to-sideline speed remind me of Bush's college tape (back when I thought he was going to be a good player).

Holcomb is also a spectacular athlete. At 6'1'' and 231 pounds, Holcomb ran a 4.51 coming out of North Carolina in 2019. His 11'0'' broad jump and blazing 6.77 3-cone make him a 96th percentile athlete compared to NFL linebackers, according to Relative Athletic Score.

Holcomb has also been insanely productive when it comes to being around the football -- earning 388 tackles in just 50 games. He was on track to have the best season of his career in 2022 before a foot injury landed him on IR. Holcomb should be ready to go and will prove to be a massive upgrade over Devin Bush.
