I don't think much of Goose, but his take is pretty easy one to come to.
Heck, I hope Dallas can break through this year but I am very cautious until they prove they are not the same old Dallas team.
The Cowboys should be better at center because Cook and/or Costa are not starting players (maybe not capable backups). Although Frederick is a rookie and I would not expect the level of play we should get from him in year 2 (barring injury). For the guard positions and RT, we are really hoping for a miracle. I am surprised people are saying Leary is an improvement before he plays a full game. I expect, if healthy, he is better than the guys last year but that isn't saying much. To be honest, I just hope they can find one solid starter between Parnell and Leary. That would leave us with only 2 positions to fill next year. I will skip over the depth of the offensive line because it is pretty bleak.
For the D-line we are hoping guys picked off the street will be able to play in a rotation. I would be ok if we were only counting on one off the street player but we need multiple and a few of these guys to be starters. I think Hatcher on most teams is either a solid starter or great veteran depth guy. I have no idea if any of these others guys can play. My biggest concern is what happens after these guys play a few games. Most of these guys have not been to ask to play a lot of snaps. Sean Lee will help clean up some of the mess because he is such a stud, but our linebackers would be so much more dominant with some big nasties inside capable of causing havoc.
I do like some parts of this team, but I have trouble predicting a long playoff run because at best from our OLine and interior D-line we hope we can maintain the line of scrimmage. I think most of us don't think we would be able to consistently win the line of scrimmage. When I look at some of the predicted best teams, I see us at a severe disadvantage on both lines. Hope to be wrong though.
