So every pick that I am aware of are as follows:
Begarin 2021 #45 (Ainge may have had more of a hand in this one)
Davison 2022 #53
Scheierman 2024 #30
Watson 2024 #54
Gonzalez 2025 #28
Williams 2025 #46
Shulga 2025 #57
I don't know how you even grade that. There is so little to work with. The focus for that period was using picks to get actual players, which Stevens did pretty well. As to the players that he did pick with the picks he had, certainly no big wins. But I also don't think it is fair to go back and say he could have pick so and so. There are always late round surprises that nearly every team could have picked but didn't. But can you conclude that Stevens is a bad judge of draft talent based on this? I don't know, I still would have a lot of trust in Brad, drafting or otherwise.
As to the most recent picks, I am perfectly happy with Gonzales and Williams for where they were taken. Shulga not so much. I view them currently as good picks, or at least as good as can be expected considering where taken.
