It does seem like a lot of big names are either on the block, bubble or already been cut.
Seeing two very young teams win Super Bowls, and the NFL is a copycat league, I expect to see more age/money cut while youth is scooped up. For teams with a strong core, this is good for them moving forward. For teams that blew it in FA the past couple of years and fought too hard to keep guys over 27, it's going to be a rough time moving forward.
Got to draft smart! Work out those UDFAs, and get your FAs cheap. It's an interesting trend for now.
