I don't think so.

5*s are not meant to be full-time day-one starters, and in 90% of cases that's not how it works out. I believe 5* means that they are capable of instant impact and will get early playing time, and that they are projected to be future impact players. However, OL is probably the rarest position for even 5* recruits to see the field early.

Alabama has plenty of 5* guys who don't even see the field for a year or two. No matter how highly touted the recruit is, it's typically not a good sign if you have true freshmen starting right away.
