That's because Parker, Bonnner and Duncan had nearly the same +/- as Finley did tonight...
While no one else had even half of his negative +/- in game 1...in fact his negative +/- in game 1 was nearly equal to that of every other player on the team...
COMBINED.
So no...his positive doesn't mean much when it is a number shared by those he started with...
His negative +/- from game 1 being 4/5ths more than any starter not named Matt Bonner(and over double Bonner's) not to mention being at least more than twice that of any other player on the bench...means everything.
Finley was an absolute whirlpool of suck in game 1...tonight he merely went along for the ride in a strong team performance....and his numbers are typical of the other starters...not standout, as they were in game 1, standout from the entire rest of the team, unless you add all the others together.
