If I rate every player on the Cowboys against the Eagles, the Cowboys win. But when I consider the team, the Eagles win.
The Eagles are much closer to a team, which has always been Belichick's forte, and the Cowboys are a gathering of individual's. I saw a team playing for their HC last night because he believes in them and has even shown that when some are replaced, they really are that "next man up" team, philosophically speaking. We are still the team.
I know we are supposed to despise all things Eagles but when I see a team so obviously beaten up with a RB I've never heard of as well as WR's and the QB really playing poorly for 3Q's but they were able to rally and pull together, the football fan in me is all about that. The fans had turned on them, the boos growing with every 3 n out and their HC fighting through that to keep his team focused, I admire the hell out of that.
Between the two teams, I'd give the Eagles a better chance, although not great, in the WC round of the playoffs.
