Do the Falcons have a splash signing left to make?

It was day one of "tampering season" today, and the Falcons have been busy! They re-signed Chris Lindstrom and added David Onyemata and Jonnu Smith, but surely they aren't done, are they? With a lot of money left to spend and a few more holes to fill, Andy Bunker and Randy McMichael think that they will definitely add more pieces, and they probably haven't made the biggest signing yet.
