The Ospreys will be captained by Ryan Jones, who makes his return, at Stradey Park Thursday evening. The Peel - Jones vs Phillips - Hook battle should be worth buying the ticket itself, and on his return, Ryan Jones would like the chance to get one over his Welsh teammate Popham in this game. The Blues start Nick Macleod at 10, as Dai Flanagan is injured. Both sides had different outcomes in the Heineken Cup, and both would find a win now, invaluable. The Dragons beat Llanelli at Stradey early in the season, so they won't fear travelling to a fellow Welsh regions fort. I predict Llanelli to win by 5 points and the Blues to win by 20+. Other predictions are welcome.
