I thought here in the wastland of time between spring training and fall practices, we might coax some of our more knowlegeble posters to give all of us a little UT Football 101. This is the fourth installment of fundamental position roles and responsibilities. Today's topic is Offensive Linemen. There is a reason this is the position in which a player is most likely (preferably) to take a redshirt. Let's find out why. What are the respective responsibilities of a center, guard & tackle? (Let's start off with the basic pocket pass play vs an off-tackle run play - using the two different blocking schemes - zone & drive) How are responsibilities changed when we add a tight end one one side - or both? What is the difference between "zone" blocking schemes vs. "drive" blocking schemes. What are the advantages and disadvantages of each (pls include variouse types of defensive fronts and which scheme is best for each front.) What (realistic) physical attributes are ideal for each position? In other words, what makes a guy a guard vs. a tackle? Center? Do these physical preferences change with blocking scheme? If so, how/what? There are many of us who know the answers to some of these questions. Speak up. If you have a question that isn't listed - or you know something about the position that hasn't been addressed - add it. The more interaction, the better.
