Yes, I'm on TLF as well. Sprints, interval sprints, and hill sprints are going to serve you much better on the lacrosse field then distance running. You're not running distance or a consistent speed on the field, nor should you in your training.
As far as your nutrition goes, I'd worry about putting on size. If you cut now you're going to end up much smaller. The season will end up leaning you out due to the increased activity. There is a huge difference on the field physically between someone that is 160 and someone that is 180. The 160 lb kid is going to be a rag doll out there even though he may be less bodyfat.
Focus on increasing your strength, eating clean, and putting on some more size. Do this and most likely you'll end up peaking physically in terms of strength and leaness when it matters most, playoff time.
