This is absolutely ridiculous and I can hear now "well if this is allowed others will write all kinds of stuff." If it's inappropriate, ok sure, but being fined for honoring one's father, who was a renowned player it's own league is simply asinine.
My other question is this to Roger Goodell, "doesn't the league have a lot bigger things to deal with outside of this?
The NFL has become known as the "No Fun League" to many including me. They are more worried about business and less about football and even the players it seems.
I don't know I could be wrong, but again these are really just my random thoughts.
