I am not Gunner, but I’ll share my take anyways…
I think the issues with Newsome are multiple…first he is a nickel corner. I suppose the Bills could move him back outside, but he’s become a nickel guy. Second he is playing on a 5th year option, so not only is the salary high, nearly 14 million for 1 year, he then becomes a free agent. So you aren’t signing Newsome and Benford. And finally, despite all of those issues with the fit, he will also cost a significant draft pick imo.
The better fit is Martin Emerson. He seemed like a great fit here draft time, he played corner at Mississippi State where McDermott has ties, and he was coming out as a good zone corner. Long arms, a little slower, tackles..he’s a McDermott corner. However, the issue is he is an also a free agent after 2025 so you run into the same issues. I could see the Browns trying to get something for him if they plan to pay Newsome, because they won’t be able to pay Emerson, Newsome, and Ward. But I think a trade for him is more realistic mid season. But I don’t think the Browns would trade a young, cheap, corner unless they want him out or are trying to get something for him before he leaves.
