Question, has he ever wrestled? I ask because it helps linemen learn to change levels as they attack
Yes, he does. Because the wrestling practices start at his school at the beginning of the year, the football players (starters) generally never go out for the wrestling team, but several including Charles, practice with the team in their spare time. Once the football season ends, Charles works out with the team, but due to a weight limit in their league (270lbs.), he only participates in work outs for "off-season" conditioning reasons. Three of the teammates he works out with (heavyweight class) have gone to the state championships and two of the three made it to the semifinals. They also take wrestling pretty serious at his HS.
BTW, ESPN just released their initial recruiting report. Charles was one of only 7 DT in the Western U.S. to get a rating this early (67), and is currently 59th of the 450 DT's in the entire U.S. to be listed by ESPN Insider. Since this rating was apparently based on his Rivals and Scout footage (which is old and included some Soph footage) it's probable that his rating will bump up into the 70's once the season starts. For what it's worth, Mike Wilcoxon who recently was offered and verbal'd to Texas, also received a 67 rating.
