Quentin Richardson - Waived by the Raptors despite a guaranteed contract, Q's athleticism has long since left him, and he is now little more than an inefficient volume shooter with occasional nights of rebounding. The Raptors opted to pay him for three seasons despite him never playing a game for them, which is no great endorsement.

After the Jones buyout came their renouncements. With the team option on Mario Chalmers exercised, the team promptly renounced everyone other than Dwyane Wade [sic] and Joel Anthony. This meant that 10 free agents from the previous season were renounced; Jermaine O'Neal, Quentin Richardson, Udonis Haslem, Dorell Wright, Yakhouba Diawara, Rafer Alston, Carlos Arroyo, Jamaal Magloire, Shavlik Randolph and Kenny Hasbrouck. Some free agents from previous seasons were also still clogging up cap space; namely, Alonzo Mourning, Steve Smith, John Wallace, Wang Zhi Zhi, Gary Payton, Bimbo Coles, Christian Laettner, and Shandon Anderson. In total, before these renouncements took place, Miami's free agent cap holds amounted to a total of $88,184,132, $24,166,800 alone was for Jermaine O'Neal.

[...] That leaves a market with few shooters on it. And those that are good shooters are either unsuitable or unavailable. Mike Miller's days of being able to defend opposing guards are pretty much over. Kyle Korver can't really do it either. I wouldn't want Quentin Richardson to attempt it. Anthony Morrow is desirable, but is not easy to get. J.J. Redick is also desirable, but he's restricted, and owned by a team who has spent extremely generously in the last two years. Roger Mason is OK, but he's no starter. And then there's Ray Allen, who, while an absolutely perfect fit for Chicago's roster, is setting records for Boston in the NBA Finals. He should be considered unavailable until further notice.
