i have not seen anything from anyone who has played that tells me that they do their job consistently well. that's just my opinion.
respectfully, i make my assessments of the guys who did not play based on the guys who did play. one assumes that the 1st string is better than the 2nd string is better than the 3rd string, etc.
so, that means that the guys who did not get any playing time were worse than the guys who did. for me, that tells me that they can be written off as not any good.
to use my own team as an example, if you are a wr at florda and you could not get any playing time in 2012, you can not possibly be any good. if you were any good, at all, you would have played. true freshman or not. although, i usually do hold out hope for true freshman in such a situation.
now, maggit, from what i saw as a freshman can play at a quality level. he was hurt all last season, so, who knows what his future holds.
AJ would not see the field at a number of sec schools. that's my opinion. he is a very good tackler when he gets to the play. but, he does not get to the play way, way too often.
