I agree entirely. Passing for SG is actually very important in a LI/LP offense. It improves shot quality and offensive flow (you'll find less 3pt/deep 2pt shots as the shot clock winds down) and while the game engine isn't quite the same as real life, you still need guys to get your big men the ball in the paint.
All of that said, in response to the original poster, you go with the first player. As everyone else said, he's got better skills across the board that you can't pass up, and the extra points in driving are (from my experience) more important than the extra IS points. I had a player a few seasons back with 12 DR and 1 IS and he made a pretty good chunk of his "driving layup" shots.
