I couldn't read the aricle becasue of the paywall, but that premise is correct IMO. The more swings you get in the draft, the better chances you have of getting a hit. Early rounds (1-3) render better athletes, so it obvously makes a difference where your picks lie. While I generally like Beane, I hate his draft philosophy of moving up to get "his guy." It costs us swings at the bat to get young cheap talent. Here are the early trade ups. QB you have to move up for, but the rest are very debatable how well we did.
In 2018 he moved up for a QB, which worked out because the Bills were lucky nobody selected Allen before us. Edmunds cost us a 3rd (we got back a 5th).
2019 sent a 5th for Cody Ford. Gave up 2 4th rounders for Knox.
2020 trade for Diggs, sent a 1st, 5th, 6th, and a 2021 4th. Got a 7th back
2021 no trade up.
2022 Elam cost a 4th
2023 Kincaid cost a 4th.
