Mayock's top 5 at each position

Based on? Just curious as to whether or not you watched YouTube cut-ups of each of their plays over several games since I know most colleges/college coaches outside a few schools like Nebraska do not release that info or at least not immediately. In other words, how did you determine who was the best players? By the way, this is not some trick question or me angling for some put down. I am just curious given the parity between your lists and most rankings out there.

I really enjoy scouting players and have watched video on almost all of them, but not all, i also base some of this off other professionals and scouts
