Boise recruited Tanner in 2010 and 2011. As you may recall, the coaching staff has turned over since then. But any scouting of high school kids is almost irrelevant four years later.
Tanner's amazing 60-yard throw early in the Boise game caught them completely by surprise. They were not prepared and did not think he could get that ball over their heads. Now that throw is the first one shown to opposing DBs. The team that will know Tanner's tendencies the best is the next one.
