It doesn't matter how many points the Cowboys scored, the fact remains that Romo's INTs cost the Cowboys those two games. That wasn't on the defense or anyone else, but Romo.
As for who is the better QB now, Romo is more athletic than Eli without a doubt. But Eli is mentally tougher than Romo. But they were both sitting at home watching the playoffs last year. So, we'll have to see which one has the better season in 2014.
ALL qb's in this league have thrown game deciding ints. not just Romo.....brady, Rodgers, peyton, eli, hell this list goes on
