A team that would want to acquire Pierce for the intention of keeping him would be a team that thinks it can contend. For example, the Nets could look for an upgrade on Gerald Wallace and send out Wallace, Mirza Teletovic, a first round pick, and maybe Marshon Brooks. I suppose the Grizzlies under the influence of Hollinger could decide to offer Zack Randolph for Pierce, Sullinger, and draft picks.
The type of team that would want to acquire Pierce is one that would want to waive him and save some money, sending the Celtics a big contract that probably goes beyond next season. A team like Indiana could theoretically trade someone like Danny Granger for Pierce and create enough cap space to sign or trade for a big contract. Or a team may be willing to get rid of a solid but overplayed player to increase their chances of tanking for the 2014 draft.
