I heard peyton testified.
not sure if peyton just testified to just facts (% graham was used in WR position vs TE, official title on depth chart etc ) or opinion (graham is a TE).
either way, that is a sure way to create division btw players and coaches.
if peyton just testified as to facts/stats - why couldnt a custodian of records do that or someone not on the actual coaching staff?
edit - seems certain precedent has been established
"Burbank said he only considered those plays because evidence showed that Graham was lined up within four yards of the line on more than 50 percent of his snaps."
"The evidence that appeared to weigh most heavily into Burbank's decision was that Graham was often defended as a tight end even when he lined up in the slot (i.e., by a linebacker or a strong safety)."
