I'll take Troy's (of Roger's or Brady's, etc) opinion on Quarterback play as golden. The further away from that subject he gets the value I place on his opinion. Not to say I may not agree, but I at least question it more. For example, his observation on Dlineman would be met with a bit more skepticism than on QB...obviously. BTW, this also applies to ex-NFL players commenting about other plays that did not play or coach their position. Just because they played a certain position does not make them an expert at all other positions as well.
