NCSF - it seems a bit naive on your part to make an evaluation of a player based on one game - you need to look at the entire body of work to make a proper evaluation.
For players like my son and Samia, their senior season actually started on January 1, 2014 at the US Army Combine in San Antonio. From there, several played in February in Texas for USA Football (against Canada), and then onto the Rivals camp in March, Nike camp in May, a dozen or so College camps in June (UCLA, USC, etc.) and then back to their HS team camps in July. Even before the season starts, players like Samia have put in a tremendous amount of work and effort.
By the time the season rolls around, many of the top players have faced a level of competition that far exceeds anything they will face in the fall not to mention the grind of attending over a dozen camps. And it is by no stretch a "cardinal sin" if their level of play falls off - again they are human beings. Maybe Samia plays to the level of the competition, maybe he was dealing with off-field issues, maybe he was bored. In the end, he will do just fine at Oklahoma or where ever he ends up playing.
