Ok this is just my opinion of course but we could be in for a GREAT year this year. This isn't about the defense which I believe will be better but I just wanted to point out some comparisons for you.
1 JJ wasn't the greatest coach when he first started here his first year he went 1-15 then followed that with a 7-9 season so if you combine them his first 2 yrs he had a 8-24 record.
Jason garret has 2 seasons of 8-8 for a combined record of 16-16 that by far doesn't say Jason is going to be a better coach but he is of to a better start
Next lets compare a couple players
Michael Irvin first year 32/654/5. Second year 26/378/2 and third year 20/413/5
Dez Bryant first year45/561/6 second year 63/928/9 and third 92/1382/12
Emmit Smith first year 241/937/11 second year 365/1563/12 and third year 373/1713/18
Demarco Murray first year 164/897/2 second year 161/663/4
Now I am not saying Dez is going to be as good as Michael Irvin or definitely not saying Murray is going to be as good as emmit smith but Dez is doing a lot better in his early years and Murray's numbers are close to Emmits if you adjust for same amount of carries.
So what makes me think we will have a great year is just this. Dez Bryant will have a great year and Murray will also or if he gets hurt again we now have his clone who I believe will be as good if not better than him .
Oh and we also have Miles Austin who will be the Alvin Harper of this team. His numbers may be better than Dez by the end of the year because of being open a lot more.
Plus like I pointed out first Jason Garret is doing better than JJ to start so that means at least 11-5 which was JJ's record his 3rd year.
