2. Gervin led the NBA in FGA only thrice. Kobe has led five times and is on pace to make that six this year.
3. Kobe has never shot 47% from the field in a season. Gervin never shot less than 47% from the field

4. Kobe shot ~44% during his prime. Gervin shot 54% during his prime. Even factoring in three-pointers, Gervin still has a much higher TS%.
5. The NBA didn't have a three-point line when Gervin broke in so "range" didn't matter. But as far as diversity of shots, Gervin > Kobe.
6. Gervin averaged 12% more points per minute during his career. And that is only going to grow as Kobe slows down.
7. Gervin averaged 11% more points per minute during his career in the playoffs. And, again, that will only rise.
tl;dr: Unless missing shots is considered a scoring skill, Gervin > Kobe as a scorer
