Brett Kollmann has a YouTube football scouting channel mostly focused on the NFL. During this 4 hour stream video he breaks down the full Indiana game tape (tOSU offense only) focused on Fields. He has already broken down the Clemson and Alabama games,  and has been moving from best to worst games. 

If you don't feel like reliving that game again or just don't want to spend that much time watching watching the same play over and over again, here's his summarized take: He likes Fields and would take him in the top 3 for sure. Indiana did some excellent schematic things that really flustered the o-line and Fields made some bone-headed plays, but he thinks his flaws are fixable. Indiana #22 will be haunting these players dreams for a while.
