Erwin deserved his chance over Clarkson every day of the week. If he didn't get a promoted to the first team squad this season, the U20s might as well pack up and go home. 
  
Of course, nobody would have predicted Sutton would be as ineffective as he has been, but with him, Erwin and Moore on the books, it really didn't make as much sense as signing Ojamaa. It's easy to say Clarkson would have been a better option now (although 1 game against us is hardly a benchmark), but at the time, I didn't hear many complaining about Henrik's signing.
