I had a similar problem at that age...
Typical days diet (long ago when protein shakes were used only by the pro's):
2 Large cheese Pizza (lunch)
2 16-24 oz steaks (dinner)
3 Large Bowls Cereal & French toast (breakfast)
Several Liters of Mt. Dew (throughout day)
1 package mac & cheese (afternoon snack)
1/2 loaf of bread (w/dinner)
1/2 pack cookies 1/2-1 gal whole milk (night snack)
I pretty much bankrupted myself and parents on food, but still no gain (98-105 lbs). It wasn't until I hit 21 that it shifted... then I gained EZ (too EZ).
I think some of it is just individual and his bod chemistry may need to mature (he is only 17 for gods sake).
The only other thing I can suggest STRONGLY is that you make sure he takes a couple rest days a week (plenty of sleep and no real activity). That means no pick-up basketball gains, no bicycling, no swimming, etc. That was one of my problems, at 17 there is a tendancy to keep going and going and going like an energizer bunny, and I seldom if ever took rest days. When I hit 21, I was forced to be more sedentary and thats when the gains came.
