Not necessarily. You would have a good blend of slashers and shooters on the court at the same time.
Starters:
Parker and Manu are your slashers at this time.
Off the bench, you bring in Jackson (slasher) with either Armstrong or Pippen and Piatkowski.
Or the Spurs could go with an all "at the basket" team with:
Parker
Manu
Jackson
Duncan
Rasho.
Or they can come with a strong perimeter team to soften up the middle with players like:
Armstrong or Pippen, Kerr
Piatkowski
Bowen
Horry
Duncan
That is an excellent blend of inside and outside players. This team could adjust to any situation.
Additionally, if the Spurs wanted to be even stronger down low (for rebounding purposes) they could have this lineup:
Parker
Manu
Malik
Duncan
Rasho
There are so many different scenarios you can go with this team. I like it.
