All sorts of paperwork flew around Thursday in Foxborough, Mass.
Here's a review of all the moves that we know about:
In their ongoing search for Asante Samuel's replacement, ESPN's Len Pasquarelli reports the Patriots agreed to terms with former Washington Redskins cornerback Shawn Springs.
They sent a 2009 draft choice to the Philadelphia Eagles for receiver Greg Lewis, who figures to replace free-agent departure Jabar Gaffney as the No. 3 target. Here's a Lewis analysis from the Boston Globe's Mike Reiss.
The Patriots announced they've re-signed linebacker Eric Alexander, safety James Sanders and punter Chris Hanson and released practice-squad linebacker Darrell Robertson.
The Patriots also lost their fullback of the past four seasons, when Heath Evans joined the New Orleans Saints.
