1. Lack depth, hence worn out in 2nd half? 2. Out of shape, soft physically and/or mentally? 3. Our coaches inability to adjust? 4. Our coaches refusal to adjust? 5. Our players are just not that good so when it really counts we get beat? 6. Our offensive philosophy to go turtle in 2nd half if we are ahead or close? 7. Other? 8. All of the above. Maybe biggest reason if all of the above.
