Abana was very raw.
It should take 2-3 years for a HS guy to be physically ready to compete. You hardly ever see freshman dlinemen or even sophomores compete at a high level, 22-23 year old offensive linemen are too physical, plus most dline recruite are 230-240lbs coming out of hs.
Juco guys should be able to contribute their first year, if they are not then you have to question evaluation.
