But the guy who should be the most concerned could be receiver Sidney Rice.
Due to earn a base salary of $8.5 million in 2013, the receiver budget may not be able to bear both Harvin and Rice, who were teammates in Minnesota from 2009 through 2010.
But Rice has had limited effectiveness in Seattle, with only 748 receiving yards in 16 starts last season. The year before, he missed seven games due to injury.
Per a source with knowledge of the contract, Rice has $3.6 million remaining in signing bonus proration, and $3.5 million of his base salary is guaranteed for injury only. Thus, cutting him would create nearly $5 million in 2013 cap space.
