I wouldn't describe Adams as "soft". "Finesse"? Yes. "Soft"? No.
Adams was a terrific player - he had a nice shooting touch, could score , rebound, pass, block shots, defend - but he was limited by two things: he was injury prone because he was always giving up about 40-50 lbs every night to whoever he was guarding, and he was in a system (John MacLeod's) where the starter's minutes were really limited.
On 2/22/1977 against Buffalo Adams had probably the greatest statistical night ever by a Sun - 47 points, 18 rebounds, 12 assists, 5 blk, 18/27 FG, 11/12 FT
