I agree we will not know until the pressure is on, but what do you want the guy to do? He has impressive film, and is nailing it at camp. He is doing all he can right now, and I have not heard anything negative about him or his attitude.
For sake of discussion and so it doesn't look like I am baselessly bashing Eddy...
He had two attempts at greater than 50 yards. He made 1 (53). This to me, shows a lack of confidence in his leg. Most of the actual top kickers in the league have around 15 attempts. Dallas's kicker went 14/17 with a long of 65.
