For the sideline stuff, again, no problem. For the on-field pout, I'd think to myself, "Oh, great -- Owens' diva attitude is rubbing off on him." And I think I've made it clear from the start that I'm not fond of the look-at-me types.
Just my opinion, and your mileage may vary.
But I find myself thinking back to what Sully (and a bunch of people here) said when they signed Owens: if he does blow up the locker room, so what? We miss the playoffs again, and ...?
And I realize I'm pretty much at that point.
