I have to believe, as Zona expressed, it helps him get out of bed each day to have a goal like playing professionally again. That deep down in the recesses of his mind or in his heart, the truth is there that he can't ever play at the highest level again, but if he lets that come to the forefront of his mind, it will make it that much harder to find the efforts towards just getting back to a normal quality of life. He has even subtly begun to express differently his likelihood of playing again, initially coming out as though he WILL play again, and at this time expressing "my dream is to come back." At 9 or 10 years old, playing little league football, I had a dream I'd play in the NFL. Every day passing was one more day closer to realizing more and more, it is going to be just a dream, but that dream and love of the game keeps you playing through Jr. high, JV and high school. His dream is likely the psychological edge he needs to train like only a professional can, but really to get to normal. Sad realization, but prayers to him for recovery, both physically and mentally.
