Either player would have the edge over the Lakers at the position.
Coach Mike D'Antoni might start offensive-minded Young with Johnson backing him up as the stronger defender.
Shawne Williams, Marcus Landry and Elias Harris, each fighting to make the final roster, bring shooting and toughness to the position. Harris still needs to develop his outside shot but brings versatility to the floor. Bryant might also play some small forward.
The Warriors also have Draymond Green, who is another solid defender and rotation player.
The Warriors also have depth at power forward with David Lee and acquisition Marreese Speights. Both Barnes and Green can play minutes in a smaller lineup, which is generally a strength for Golden State.
Veteran Jermaine O'Neal signed this summer and though in his prime he was a power forward, he could better suited in his later years as a defensive center.
Power forward is somewhat up for grabs with the Lakers, who could start Pau Gasol, Jordan Hill, Chris Kaman, Shawne Williams or even Wesley Johnson. It's an area in which D'Antoni appears willing to experiment initially.
Gasol might be better than Lee, but not dramatically. If he's not the starter for the Lakers, Lee and the Warriors have the advantage.
When healthy, Andrew Bogut is one of the better defensive centers in the league. After a couple of freak injuries earlier in his career, he appears to be on the right track for the Warriors.
If the Lakers start Gasol at center, he's more skilled offensively than Bogut, but not by a large margin. Chris Kaman gives the Lakers a nice offensive option but he's not as strong a defender as Bogut.
The Warriors also have O'Neal and will develop rookie Ognjen Kuzmic. Reserve center Festus Ezeli is sidelined with a knee injury.The Lakers will also play Robert Sacre and Hill at center.
Neither team has a dramatic advantage at the position.
Who is better?
The Lakers have the clearest advantage at shooting guard, providing Bryant returns healthy, otherwise the Warriors are close or better than the Lakers at every other position.
Golden State won just 47 games last season before a solid playoff run. They'll crack 50 this year and possibly 55.
The Lakers are likely in the 40-50 range, with too much riding on the surgically repaired Achilles' tendon of Bryant.
