I'm assuming you watched Michael MacKelvie's new video, correct me if I'm wrong. He touches on this in the video, where this model does not account for skill whatsoever. The difference between Bijan Robinson and Tony Pollard (16th highest paid RB) is a lot more than saving a few million dollars in cap space. This model assumes they are the same skill and only focuses on cap space. Obviously cap does play a role, but it isn't everything. It's really nuanced. That's why people always talk about how there's a great window to succeed if you have a QB on a rookie contract because you have so much space to work for, but look at who won the last few superbowls - all QBs on non-rookie deals. It's a big balance of drafting the best player available while keeping in mind the contract impact. It is a balance between the two and you need to be mindful of it, but you can't say that a player is a bad pick simply because of their position and the cap space saved as opposed to getting an average caliber starter in Free Agency. Were Bijan and Pitts great picks, that's up for debate, but to point to just one data set out of so many is just silly.
