The Force have lost two very good players in McMenimen and Cummins, they will need to recruit well just to replace those two.
McMeniman has spent more games on the sideline in the last two years than on the field. His form has been patchy as a result. I don't actually think we are losing too much in McMeniman. Cummins, Hayward and Longbottom will be much bigger losses.
Completely devils advocate here, but given the trouble the Force have keeping their base intact, I wonder what the scene would look like if Melbourne had gotten the franchise before Perth those years ago.
The distance can be too much for some guys, especially leaving family on the east coast.
Note: I'm not picking a fight, but while the force have had a great year, fuck they've lost some blokes! Perhaps as a result of them getting exposure at this level.
It would certainly be interesting to open a window into a parallel universe where that had happened. But personally, and no offense intended, I think you are missing the issue. Topline players almost invariably get picked up by the franchise that developed them. Where the Force (and Rebels) have had to recruit from elsewhere, we are either getting in early (Luke Jones, David Pocock, James O'Connor, etc) before the Tahs and Reds are ready to take a punt. Or we take a gamble on an outsider. We have a big turnover of players because some of the gambles don't pay off. Some of the gambles do, but then we (the Force) made the mistake of not building a strong enough culture (see Brumbies) to make more players want to stay. Some have chosen to stay through the tough times and they have been great for us.
One of the really difficult things in Super Rugby is that we have 5 teams and yet only ~30 players get ARU top ups. It is hard to retain those players who are not in Wallabies contention and unlikely ever to come back into contention. If half of the Waratahs squad weren't on top-ups, would they be able to retain players as easily?
Back to the Rebels, and correct me if I am wrong, but next season won't there be only 2 inaugural Rebels players left (Luke Jones and Laurie Weeks)? Provided Pek Cowan re-signs, we will still have two inaugural players after 9 seasons. Is there good reason to believe it would have been any different back in 2006?
