We may not always know exactly what Belichick, Caserio and the Patriots will do, but we do have an idea of what they won't do.
New England is set at multiple positions barring injury or trade. It's fair to say that we can expect some positions to be left as are with no additions being brought in to compete.
It appears there will be depth behind Tom Brady this season with the addition of rookie Ryan Mallet. There's no reason to believe the team would bring in another signal caller; in fact, it may elect to trade Brian Hoyer and ride with two quarterbacks just as it did last season.
If an addition is made at running back, it won't be anyone but Kevin Faulk. The team has four capable and young ball carriers, and most likely won't look to add to its crop. Keep the name Eric Kettani in mind as well, he's been on the Military/Reserve list but should be available this season.
There will be no additions made to the tight end group, at this stage it would make no sense. In fact, it's unlikely that the team will commit four roster spots to the position, but time will tell how healthy Alge Crumpler is.
Cornerback seems to be solidified, and if the Patriots were content with what they had last year, they should be more than happy with the return of Leigh Bodden and the addition of Ras-I Dowling.
Inside linebacker is pretty set as well, with Jerod Mayo, Brandon Spikes and Gary Guyton holding down the fort.
