WR Reche Caldwell isn't a big name, but for now he's the Patriots number 2 wide receiver. The scary part is that 2005 was Caldwell's first season that you could even consider "decent". Caldwell's first two years in the league were marked by a poor work ethic, and when he started to turn it around in 2004, he tore knee ligaments six weeks into the season. You can check out his career stats at Pro Football Reference
, but it looks like he regressed in 2005, with 28 catches for 352 yards in 16 games, after 18 catches for 310 yards in just 6 games in 2004.
I suspect (and hope) the Patriots are far from done at the WR spot.
