Question: cap saving roster moves

I was wondering, looks like cutting flacco will save 10m in cap space, and im assuming he wont want to back up lock so i feel this is going to happen. The other big cap hit is ronald leary. Is he worth 8.5m? I know our OL needs as mu h help as we can get but I didnt get to see as many games tjis year so im wondering if he earns that or if we are better to try and restructure or release him to try and get a center or LT? 8 penalties and 1 sack arent bad but im wondering what people who has watched him closely have to say
