All across the NFL owners are becoming more involved in football operations. This is true in Tennessee, Carolina, Philly, maybe even New England. It's the trend.
I don't know why, but if I had to speculate, the franchise value of $5-$7b for most of these teams has made this into much more than what it used to be. The NFL was a side gig and a hobby for many owners who had businesses elsewhere. Now the NFL has overwhelmed their business interests. Obviously this may not be true for some of them, but for an increasing number it is.
