Also a team balance thing. It appears that Bradburn wanted to lengthen the batting lineup, so Yovich / McGlashan batted at #7 / #8. Add in the reliable Aldridge and Arnel, and this left a place for only one more bowler. With due respect to Joey, he has the odd expensive day, so for team balance the extra bowler needed to be a steady / workhorse type. Step forward Bradley Scott or Bruce Martin. No space for Davis / Verma etc....Matheison was injured for a good part of last season, so tahat basically explains him. Not to sure about Verma though, however he was in the squad for one of the early season FC games last year. I'm guessing Bradburn just wanted to stay loyal towards the older guys (Bradley Scott mostly) and I wouldn't be surprised to see him gone come next season either....
In 2011 I'd prefer to see McGlashan / Yovich at #6 / #7. Aldridge is a good enough all-rounder to bat at #8. Then Arnel + young fast bowler + spinner (have we seen the last of Bruce Martin?).
