You should be concerned about the level of competition. He won't be little leaguers in the minors. The conference SDSU plays in is very weak. Their non conference schedule is very weak. One game "series" vs Long Beach and Fullerton, and USC aren't going to cut it. And besides Stras won't pitch in those mid week games against the tougher teams.
If were going to get him I want him pitching to weaker competition. Right now, he has a manager who knows he's gone next year and has every incentive in the world to get what he can out of that arm this year. Weaker teams are less taxing.
