In the past 7 years, only the 2022 QB draft class is clearly worse (at draft time, I wouldn't put money on 2025 ending up worse than 2021).
Ward and Sanders are the only guys who will likely go top 10, and they are not at the level of the top guys in 2024, 2023, 2021, 2020, 2019, or 2018.
Allard and Nussmeier are staying in school, so the depth are Milroe, Beck, Ewers and Dart (probably). The depth is relatively fine. Obviously, again, stronger than 2022, but not clearly superior to other drafts, and clearly weaker than 2024, 2023, 2021, 2020.
The Raiders are in a better spot than most other teams though. As long as they don't accidentally win a game, they're picking top 2, which means they'll be able to pick one of the obvious top 2 guys.
I think Sanders should be a starter, but I'm not sure how good he will be at the NFL level. He has very good accuracy, doesn't get skittish in the pocket, and seems to understand the game fairly well. Oddly, despite being the son of a transcendent athlete, his tools are a bit lacking. He doesn't have a particularly strong arm, and he's not very fast.
Ward is a gunslinger with a lot of arm talent. I personally think he's more talented than Sanders, but I do think people are pretty split on it.
I think there is a case to be made that both players are worse than all 6 QBs that were picked in the first round last year. But last year was special.
