If I'm gonna agree to pay $36 million over the next 4 years to Biedrins, a 5 ppg, 8 rpg, 1.3 bpg center who shoots 55% from the line, can't be relied on to play more than 25 minutes a night due to foul trouble, and has missed 70 games in the past two seasons, and give up Perk, a 25-year-old who is one of the best defensive centers in the league and started on a team that won a title and made the Finals over the past three seasons, I'd better be getting Anthony Randolph and maybe Azubuike too. I don't care if Perk blew out his knee and is gonna miss some time. Biedrins has done nothing in this league and is already way overpaid.
And keep in mind, those low numbers came on a team that plays a fast pace that inflates scoring and rebounding numbers, and was one of the worst defensive teams in the NBA.
