So what you're saying is that the premise of your argument that a true freshman offensive lineman can contribute right away is based upon the example of a skill player (and not just any skill player, a player so skilled that he is currently one of the most productive backs in the NFL)? Explain to me again how this supports the assertion that an O-lineman can start as a true redshirt frosh. An important note...I'm not trying to say that no frosh could ever start on the OL...I'm just saying your logic is full of fail. I'm also trying to point out that this premise you raise isn't tied in any logical way to the assertion made in your OP.
Yes, as I said, we are all dazzled by the nifty logical two step you are offering us. Dancing With The Stars level material here.
A tip. When trying to slam the offensive line with a link to the article, make sure it actually backs up your putdown. And then when you want to change the topic to an argument about whether true freshman O Lineman are capable of contributing, try to find an example that includes a true freshman offensive lineman (something that another poster was able to accomplish with a simple Google search).
