Bud,
Even if we just resign House and stay pad not adding another guard, I'd have to think very well if I want to resign Allen or leave the spot open.
Rondo, Pruitt, House, Allen, Giddens. If an injury happens, we can always add another guy, depending on who gets injured. There are always plenty of guards available for the min sallary, especially SGs. Also, this gives us more flexibility if someone in our frontcourt goes down. I mean, imagine we sign Zo as our backup center. Imagine if he suffers an injury. What to you do next?
