It's also not good when your snobby QB whose ego is very precious must select certain players over the others he ignores, to run said plays.
Pre-Giselle, Brady was not doing that. He was running the offense and hitting the open guy. Now, he's so concerned with stats by his younger buddies who play in 10 fantasy leagues convinced him he was doing it all wrong.
You don't seem to get that Brady's Diva issues, pretending he had to have All Pro WRs 1-5 and All Pro TEs, is what the problem was. His ego told him he was so great, he's entitled to that.
There is a salary cap. You can't have sustainable teams for decades that are playoff contenders by procuring All Star offensive players. You can do it for a year like Denver did in 2015 on defense, but look what happened to them.
No one GM fielded more competitive teams over 20 years than Bill Belichick. And no one coach fielded better teams than him overall. This isn't a video game like you and others think it is. Try learning the sport first.
