Some very good posts here. I love posts that are based on actually watching the player and not from some comments or lack of comments by people like Broaddus or ESPN guys.
I've watched all snaps that Parnell has ever taken with the Cowboys in both preseason games and regular season games. He is really fun to watch. He can physically dominate defenders in ways that Free has never been able to do. He is much stronger than Free and a little quicker as well. Some people say that he play to upright, but when he is holding his ground or the defender is moving backwards I don't really care if he's playing a little upright. When Jerry said they Parnell had the strongest "punch" ever measured by Woicik, I believe that is probably true. Punch is not just weight room strength, it's combination of speed and strength.
Parnell was injured all of last preseason which was his one real chance to beat out Free. In the one preseason game that he played, he was visibly limping between plays but still dominated the Bengals rookie 2nd round DE. He even dominated All Pro Geno Atkins on one play. I bought the extra package to get the Preseason games on the All-22, but they become unavailable after the season starts.
Parnell's biggest problems have oddly come when he has played as an extra TE. He's has a tendency on short yardage running plays to go for the kill shot which sometimes results in whiff.
Reports came out in 2012 that Callahan wanted to bench Free and start Parnell but that "management" wanted to stay with the more experience player. The compromise was the rotation between Free and Parnell for the final 4 games of the season. I'm not certain is "management" was Garrett or the front office. Jerry has had a strong tendency to want to play the guys with big contracts even when they are not performing.
All media comments about Weems overtaking Parnell have come from 1 source, Broaddus. Broaddus is the same guy that reported that Carter was moving to the SLB which it turns out was just his idea. Marinelli clearly stated that Carter would be competing at WLB.
I do think Weems has some upside. In the preseason, you could see that he has NFL physical ability, but was raw as a player. He has a build that would make him a good Guard also. In the 2013 preseason, Weems reminded me of Leary from the 2012 preseason. With both you could see NFL type physical ability, but they were raw as football players. We never saw NFL physical ability from guys like Arkin.
I've posted about is before, but the OL coaches schemed around Free's weaknesses in 2013. It was a brilliant job of coaching. I would love to see Parnell and Weems challenge Free in training camp; although, with Free having a significantly bigger contract than those 2 guys, I don't know if the Cowboys management would really bench him.
