Wing Johnny McNicholl, who made his debut for the Crusaders this year before succumbing to a serious ankle injury, will be available next season which will help in this respect (he is likely to just miss out on Canterbury's campaign), but the addition of a power-player such as Savea would lend more balance to the Crusaders backline.
So, if Savea says no, the Crusaders will be in the market for another outside back at least.
But while they wait on Savea's decision, the franchise is quietly confident it is building a forward pack which will serve them well for many years to come.
Forwards such as Luke Whitelock, Jordan Taufua, Matt Todd, Dominic Bird, Joe Moody, Jimmy Tupou and Ben Funnell are all extremely promising. Flanker Todd, who made his All Blacks debut in June in the last minutes of the third test against France, continues to improve even after making his Super Rugby debut back in 2009, while standout lock Bird - all 2.06m of him - suffered the misfortune of tearing his pectoral muscle on the eve of the series against the Tricolours. His place went to Jeremy Thrush instead.
Loosehead prop Moody has been included in a couple of All Blacks training squads this year, while loose forward Whitelock has been on the All Blacks radar for a couple of years, despite being only 22. Hooker Funnell added impact and energy when replacing Flynn. Codie Taylor, another hooker, is also promising but is out of action with a similar injury to Bird's. Both Taylor and Bird will be available for the Crusaders pre-season campaign.
Of that group the oldest is Todd at 25. When placed against their older teammates, proven All Blacks Wyatt Crockett, Corey Flynn, Owen Franks, Sam Whitelock, Luke Romano, George Whitelock, Richie McCaw and Kieran Read, the Crusaders pack looks in good shape for next season.
The trick for Todd Blackadder, though, will be to keep the young bucks happy as he continues to develop them. Once they begin to get game time it becomes an expectation and they can be easily tempted by other franchises if the minutes don't add up to their satisfaction.
One of those looking from the outside is likely to be Hurricanes coach Mark Hammett, a former Crusader who successfully tempted All Black prop Ben Franks away last season, a successful move for both player and franchise.
If Savea signs with the Crusaders, Hammett could have a greater motivation to pinch a couple more of Blackadder's forwards.
