I concur with the general consensus: rebounds underpriced, overall salaries at the top end way too low.
Running a few formulas in Excel:
Average old salary of all players: $2,519,739
New: $2,620,389
Overall 3.99% increase in salaries
Average old salary of top 10%: $6,505,367
New: $5,959,052
Overall 8.40% decrease in top 10% salaries
Biggest % increase: 68-69 Randy Mahaffey's salary jumped from $272,212 to $1,015,720 - a 273.14% increase.
Biggest % decrease: 64-65 Wilt, from $7,235,221 to $4,503,611 - a 37.75% decrease. You could couple him with the 96-97 Rodman and have 3,734 minutes at the C position covered for $7.5 mil.
