PG Diaw 6'8" 215lb
SG Childress 6'8" 210lb
SF JSmith 6'9" 210lb
PF Harrington 6'9" 250lb
C Walker 6'9" 245lb
Don't know if this lineup could win, but it would be fun to watch five guys who are all 6'8" or 6'9"
Of course, Walker is a little small for Center, but he is a very good rebounder. He played some Center for Dallas last year and pulled down double digit rebounds in 27 games. If Walker is good enough to start at Center in the Western Conference, he can be respectable in the East.
Diaw, Childress, and JSmith are fine rebounders and Harrington's not bad either. Diaw & Childress can help on the boards with their long wingspans and JSmith will simply jump over people.
How would you like to be a 6'2" guard trying to drive the lane against this crew?
