At the end of the day, football is still a mental game despite what game scripts, player measurables, analytics etc. say.
Arian Foster = UFA
Edelman = College QB
Antonio Bryant = 5th Rd Pick
Kam /Sherman = 5th Rd Pick
I strongly believe that an average/ below average player put in the right situation with great coaching & personal determination can be damn near unstoppable sometimes. There's no better example of this than comparing Sammy Watkins and DeAndre Hopkins if you're familiar with their college-to-professional arcs.
