Gallo's shot will find him. He has all the potential to be good but dude probably wont be anywhere as great as Dirk, ever. Plus we all know DJ's boy bargnani is the heir to Dirk

. Oh and to answer your question, it didnt take Dirk long at all. His rookie season was the 50 game lockout season. He averaged something like 17 and 7 in his 2nd season.
Knicks need a real point guard to direct the offence, this jacking 3s business can only be bad for Gallo's development. He's taken 19 shots so far in preseason and 12 of those have been 3s. Thats a really bad ratio.
