Honestly, i wouls rather have him play end. His combination of speed, size, strength and pass rush ability would wreck havoc with blockers. Tying up lineman does not always mean standing thereholding position.
As i remember, where to play Peppers was an issue we bat back and forth before the 2002 draft. do you add say 10-15 pounds onto him and make him an explosive DE or have him as an OLb at around 270.
