I signed up for the cheaper 1 yr version of PFF (around thirty dollars) and it offers some excellent draft tools beside its basic coverage of NFL player grades. The NFL website also offers a Mock Draft simulator for 2022. Both are fun to use just to get a "feel" for who might be available at our various pick selections...and both offer the ability to "trade" picks...
I've messed with several Draft/Mock simulators and traded up with Detroit to land #2 pick overall (still drew an F grade for the trade...swapped R1 and R3 2022 picks and a reluctant R1 and R3 from 2023) to grab A. Hutchinson(A+) to give our d-line some "Bite". I used both of our R2 picks to grab QB D.Ridder (A) and QB K.Pickett (B-) for serious competition with Lock...I used our R4 to grab Domann (A) as CB and both R5's to grab T.Walletsko (OT)(A) and Z. White (RB)(B+) while using our R7 pick on another young center D. Kramer (A-). PFF gave me the player grades with an overall grade of A-. Free Agency/Draft has become fun again...
