A title team shouldn't carry more than 3 projects on a 15 man roster. Between Hudson, Pruitt, Giddens, Walker; we should only keep 3.
Heck, Tony could also be thrown into the project pile, considering all his "untapped potential". Seriously his only value is wing insurance and trade fodder later on, when some team has a fire-sale.
To expand: Tony and Scal are insurance (11th, 12th men). If Baby is kept, we still need 1-2 solid rotation players.
