Some thoughts:
as others mentioned QB is different to all other positions. Leadership, quick decison making, composure under heavy pressure are king.
Defence won the this superbowl, guys like Ndomekun Suh and VIta Vea are 300 and 345lbs!
…its fair to say their lifting is"quite heavy"
Brady does actually do deadlifts, rows and loads of overhead press just with. band atatched to a mini barbell. Just no free weights.
Sprints a ton as well -bike, prowler, sled work.
Not to mention sand sprints on his own private beach
Good perspective here also by Dan John…
