The thing I find most odd is your continued obsession with Doug Free vs Jermey Parnell.
One player is still with the Cowboys, while the other is not, and all of your hand-wringing and number crunching won't change that fact one bit.
Based on your posts and track record, I firmly believe - and I know I'm not alone - that you're rooting for Doug Free to struggle this year simply so you can tell this board "I told ya so!". Your being right is more important than this team's overall success.
No matter how much math you provide, Parnell is not coming back.
I've posted this before, but I'll say it again. It really was not about the specific players per se. They just happened to fit as an example of something I wanted to pursue. Generally, my contention is that fans and a lot of media don't or can't analyze players for themselves, especially at positions like OLine. Most people need someone telling them that a player is good before they can recognize it.
Also, fans/media have some rules of thumb that they often use as absolutes without really analyzing the situation. For example, many people assume a player is crap if he has not become a starter or gotten the media seal of approval after a certain amount of time. Obviously, the time frame for Parnell needed to be different, but people don't really think in those terms. After he had been around a certain period of time, they assume he must be crap if he has not become a starter. It's similar with a guy like Escobar right now. He has been good when given opportunities, but people assume he is crap because is not starting or getting a high number of targets.
The Free/Parnell debate also showed me which posters will actually study the players and not just go by the media's opinions. I have found it fascinating how many people have super strong opinions on the Free/Parnell topic but have not studied the game footage. There were a couple that did. Primarily Fuzzy. He reviewed Parnell and gave his input and he has no bias in favor of the player from what I can tell.
The other aspect is that it was an interesting story of how the Cowboys took a college basketball player that was about 280 when they signed him and developed him into a huge OLineman capable of being a decent starter. The media missed that story because there was nobody to tell them he had developed into a good player. Callahan said in an interview last season that it was a great story and should get more media attention.
I had some of the same debates about Ron Leary when the Cowboys first got him. There was one particular poster that I debated with that said Leary was complete crap. Even after Leary started in 2013 many people said that Bernadeau would likely be the other starting OG with Martin. Even now many fans/media don't give Leary much respect. primarily because he was not a 1st round pick and does not get much hype. They assume that Collins will automatically replace him even though most of them have never seen Collins play a single snap.
I will likely develop another pet cat or two this year. Maybe Weems or maybe a DLineman. Maybe Wilcox. I said before OTAs to not count out Weems despite the addition of Green and Collins. Now that Broaddus has given him one positive paragraph, people are starting to post about him and how he is probably in the lead for the backup OT job.
The bottom line is that many of the most vocal message board posters with the strongest opinions are the people that do the least work to backup their opinions. I like to counter those people with my opinions which are based on actually studying the topic.
