What has he done lately?
whats the difference. Thigpen basically only plays special teams. You can use Hester as a receiver if needed . You don't want him as a starter but he brings more to table than Thigpen
Is he still a good returner?
This one takes the cake of "Release was-a-superstar vet, lets sign him".
Hester is a PR/KR specialists and a washed up one at that. Toss in that the KR is basically eliminated and you have a player for PR's only.
Also, Hester sucks as a WR so stop trying to convinve yourselves he could step in.
The guy is a speed demon and at 31-32 years old has lost a step or four.
