Whilst it would have been nice to have a bit of explosive pace last night - I don't see anything to be concerned about just yet.
Theo is still very young and inexperienced. He had only limited opportunities at Salford - especially toward the back end of his time.
Basically he's still in the development phase of his career. Further along the line than Knowles and his cohort - but not the finished article.
Saints are very proud of their junior development system. So it shouldn't come as a surprise that Cunningham has opted for Knowles this early in the season. Had Theo been immediately promoted above kids Saints have invested a lot of work and faith in it wouldn't have sent a great message. Pull your tripe out in what was an excellent season for the kids and your reward is playing second fiddle to a talented but very green youngster who did precisely WHAT last season?
Sometimes there are bigger issues than raw ability. We have a long season ahead of us and Fages will get plenty of opportunities to show what he is capable of.
