So the premise is if you never played or are worthy of carrying their jockstrap then your opinion is worthless?You guys calling out the line probably never played and certainly are not worthy of carrying their jock strap. Colby and Jones are Sophomores and Steven's was a Freshman.
If that is the case later on is this thread I believe you claimed that you watched the games and in your opinion you saw several good things in the OL. Unfortunately since you probably never played OL at Iowa or carried their jockstrap your opinion doesn't mean anything either.
Might as well shut these boards down to a very, very, very few(any?) who meet your criteria to have an opinion on these type of things. Age and knowledge should tell you that you don't need to have been proficient at something to have a valid opinion on the quality of the effort.
If I watch trap shooting and one person hits 23 of 25 and the next person hits 1 of 25 and the next hits 22 of 25 it's safe for me to form an opinion that the person who hit 1 of 25 probably isn't very good whether I have fired a gun in my lifetime or not.
I get tired of the incessant complaining far more than the 'if you have never coached or grab a whistle or if you never played' but both actions are tiring. So practice up on your age and wisdom technique and use it a little better next time because I like your perspective on most things.
