Travis Fulgham on the Eagles for me. Granted, they were practically left with practice squad WR's at this point, but everyone was super hyped on the dude as he had like 3 or 4 weeks of pretty great play (comparatively speaking). Then he just disappeared one day, not even playing poorly, just not playing at all.
Edit: Scrolling down I see he was already named, but ah well.
Suddenly the NFC holds 4 of the top 5 spots.
