I have zero problem with a guy like Frank Jackson skipping a mission. But you can't go making blanket statements like that. Everyone has a different story.
As for Taysom, he does not fit into the Frank Jackson mold. Taysom was a mid-level recruit out of high school. His only other P5 offers were WSU and Arizona. The fact that he even got offered by Stanford is a pretty strong testement to Jim Harbaugh's ability to spot talent.
