Wrong year for big Chargers spending - Michael Gehlken (paywall)
The numbers are out on Danny Woodhead, and like the others, they provide a dose of reality.

PFF's 2009 First Round Re-draft - Khaled Elsayed
Notes: The Chargers saw English as a long-term replacement to the fading force that was Shawne Merriman. He wasn’t. Remarkably still with the team, he plummeted down the Chargers’ depth chart and has struggled to get playing time. Even when he has been on the field he’s failed to produce and must go down as a wasted pick. Re-Draft: It may be a little high for him, but if you’re desperate for pass rush then Paul Kruger is the best guy to fit in their 3-4 scheme.
