I find it hard to believe he has ever made 17 free throws in a row. Hard to believe even in an empty gym, let alone NBA games.
Shaq's career FT% is higher than Ray Allen's career 3-point percentage, 52.7% vs 39.6%. Statistically, Shaq is way more likely to hit 17 free throws in a row than Ray Allen is to make 17 three's in a row. Would the latter surprise you at all?
Shaq broke the single game record for free throws without a make in one game previously held by Wilt Chamberlain.
Yes it would surprise me greatly if Ray hit 17 bombs in a row in an NBA game, not in an empty gym, but they are different circumstances. FT are technically the same. 3PT shots vary depending on the spot, defense and how much time he has to put it up. It's really apples to oranges. In an empty gym, I would say Ray makes 3PTers at a better clip than Shaq makes FT's.
I don't know what the record is for most 3PTers in a row, but I highly doubt it is 17.
