The Bucs are almost through with their first substantial work of this offseason, this week's three-day mini-camp. They will work out just once today. In this final, voluntary practice, it appears a few guys are missing. CB Ronde Barber is among those not on the field. No sign of TE Kellen Winslow, either. He opted not to practice Wednesday but was present. Don't see C Jeff Faine, either, but he told us in a text message his back strain is very, very minor and his absence is precautionary. Stay tuned and we'll share more info as we learn it.
