9. Joe Johnson. The Hawks are expected to offer him the max, but Johnson could yet earn a six-year, $125 million elsewhere in a sign-and-trade with the Knicks or another team, which could send a second-round pick to Atlanta and leave the Hawks with a highly-valuable $16 million trade exception to be used over the next year. Every team with cap space covets Johnson in addition to teams like the Mavericks, who hope to acquire him in a more traditional sign-and-trade using the expiring contract of Erick Dampier.
