He never was able to lead his team to a repeat championship. Basically won 4 1/2 championships in NBA down years and got mollywhopped the next season when the target was on his back.
Never was a great scorer.
Never was a good one on one defender, but was an above average help defender.
Never was a great shot blocker.
Never was a great passing big man.
Never had to guard the opponents best player as he routinely ducked the bigtime bigs by switching between C and PF (wherever was easiest or most convenient for him at the time).
Pretty much just above average or average all around.
He had Bruce Bowen guarding all the perimeter great players the Spurs went against.
The guy has been a B-Average player his entire career. Never extraordinary at anything, just pretty good at everything.
