Another area where Australia have a big advantage is on the bench where they have three or four game changers where the Lions, struggling with injuries, are lacking someone capable of making a difference.
In troubled Kurtley Beale they have a player who, on his day, is good enough to warrant a place in any side in world rugby.
The big question is how close is he to match fitness and top form given he has played just one game, at Sydney club level, in the past couple of months.
Given they have three capable 10s on the bench, Australia has the luxury of picking Pat McCabe on the bench. If the Lealiifano experiment fails, he provides a power running alternative who will shut down the inside channel defensively.
The respective bench replacements are both pretty solid units, with Dan Cole and James Slipper two of the highest-rated young props in world rugby.
In the backrow, the Wallabies have the hugely talented Lian Gil who, if introduced, will free up Michael Hooper to showcase his attacking abilities. Gil is a potent scavenger who has gone from strength to strength in the past 18 months.
The Lions made the surprising selection of Dan Lydiate, a Warren Gatland favourite, to provide backrow cover. I just don't see him as an impact player off the bench and would've started him with Croft on the bench or picked Sean O'Brien on the bench. Lydiate is a closer, at his best shutting down the opposition.
Speaking of closers, the Lions have also chosen Owen Farrell who, like Lydiate, will be great to spring off the bench if the Lions get a lead but not someone who will lead a fightback if the Lions find themselves chasing the scoreboard.
The one game changer in the Lions bench is the dynamic Ben Youngs. His pace and distribution will totally change the Lions shape if he is sprung from the bench.
The other surprising selection is Sean Maitland who has looked poor in his appearances on tour thus far. Is this a move to appease the Scot's as he is the sole Scottish representative? The Lions would've been better served having Rob Kearney as an option to counter Folau's aerial threat or Simon Zebo to provide some spark.
