I am not sure that "superstar-laden" is an accurate reflection on previous years. We had a few, but were not exactly a Real-Madrid type "galactico" team. Some who might now be considered superstars were not so when they joined us (e.g. Nathan, Gopps) and developed at Wasps.
This year looks like a good balance between numbers and quality (or potential quality), perhaps some longer-serving players who were with us for the move to Coventry were on larger than normal salaries and now there is more money to spread about.
I think it could be another slightly shaky year as it takes a while to gel as a team with a lot of new players and we are a bit behind the development at Saints and Gloucester, but if we can use the numbers and avoid the injuries and develop as a team during the year then there should be a steady improvement leading to a better year then the one just gone, and hopefully better ones to follow.
Optimistic as ever of course.
