The Bengals' cap plans

Heading into the start of free agency this offseason, the Cincinnati Bengals were identified as one of the teams with the most room under the cap limit; ergo, some believed that there could be a spending spree. Members of that cohort may not have been paying attention to the Bengals' actions in recent seasons, however, since that's not really how this club does business. Instead, the Bengals have focused on re-signing their own free agents, and it's been estimated that the team has spent between $33 and 34 million in cap space in so doing thus far, with deals for Andre Smith and Terence Newman likely forthcoming. So what's the long-term plan?
