An individual sure can be influenced, in Tim Donaghy it also cost him time in prison. When talking league wide no I don't think it is the case in any of the major sports
I was having a bit of fun...
But the point stands. I am not saying there is or isn't. It most certainly is POSSIBLE.
My FEELING about it....is (for example) Jerry and GODell publicly feuded...and Zeke found himself at home for 6 critical weeks in 2017, against his own female counsel. Jerry had a great run in 2016, poised for another solid run in 2017. GODell put the kibosh on the that oh what a coincidence. Jerry's PRIZE...shamed and sitting.
So why wouldn't that attitude permeate up and down the NFL organization...either through discreet edict or just general corporate atmosphere? I am sure the suspension was a prominent subject in the offices and meetings. And water cooler.
It doesn't HAVE to be a direct order in a memo from GODell to the line judge. It also doesn't (necessarily) have a tie in with Vegas. Although that *is* big business follow the money!
If GODell gives favor to a certain team....why wouldn't everyone else downward follow the lead? IF GODelll gives disfavor....follow the lead.
I am not saying this is what happened/happens. But I know human nature.
