as for other wing additions, i like azubuike and delfino. delfino is restricted, and i think buike might be too (from what i gather from warrior fan). but i think both have the potential to fill in nicely. delfino is young, big, and athletic (25 yrs, 6'6", 225), is a great slasher, has good range, and is a solid defender. problem is he has only really exploded this year, which is his contract year (too be fair though, he was stuck in detroit). also, his shot selection comes into question at times and his shot is a bit streaky too. but i think he would fit very well in the spurs system and mesh well chemistry wise too.
buike is a bit more of an unknown. it all depends as to whether you believe nellie-ball can translate to actual basketball lol. if so, the kid has the same physical tools that delfino has, and then some. with what he lacks on the defensive end, he makes up with unselfish offensive play (a bit of an oxymoron in nellie-ball). my biggest issue with buike is that he is last on the warriors in +/- this season (something like -52 this season). but that might straighten itself out over the course of an entire season, so i wont hold that against him yet.
