While it's assumed it was because Bradshaw didn't get the ball in the redzone, there is another theory
Ahmad Bradshaw has a touchdown today, and touchdowns are nice. Plus, the Giants are beating the Redskins late in the fourth quarter. That's nice too. But for some reason, Ahmad is grumpy. Like, he's pretty mad, guys.
Oh, I get it his name is Ah-mad. Haha I didn't even notice that before. So why is he upset with Uncle Coughlin? Well, presumably it was because Bradshaw didn't get a touch inside the redzone. But that's not true. Sources close to the situation are indicating Bradshaw went out of town recently and needed someone to watch his cats for the weekend. He asked Coughlin, who of course said yes because if you say no to your friend about something like watching the cats, you're not a very good friend even though it's super annoying and not fun at all.
But I guess the water bowl was empty and the cats were meowing a whole bunch when Ahmad got home. So Tom totally thought he could get away with going over there once and filling up the bowls then not coming back because cats are pretty much the most set it and forget it animal ever. So Bradshaw was all mad and stuff, naturally, because he asked his friend to help him out and he lied.
Hopefully, they can talk it out and get coffee later. Friendship is important.
