"It's been a normal week for me - fullback and halfback," he said.
Castille has been a fullback AND a halfback for the past two seasons, when healthy of course. As a true freshman, he started his first game ever as a fullback
Castille claimed he hasn't been bothered by the knee he tore two ligaments in last October, but that the brace he wears is a constant nagging reminder.
"I haven't had any blowup (swelling) since I've been going," Castille said. "I actually got hit on it Saturday (against Southern Miss). I took a pretty good shot and it was fine. I don't have any questions now, other than when they're going to let me get out of this dad-gum brace."
"Physically (the brace) weighs on you. This probably weighs a pound, maybe not even that. You've got it wrapped around your leg; it feels like it's squeezing the life out of you. You feel more free without it."
Castille hoped he would have to wear the brace for only a couple of more weeks before he is able to shed it, but he faces the daunting task of getting that cleared the Alabama's athletic trainers.
Is there any post-surgery soreness that comes naturally with the type of injury he had? Apparently not for the lucky Castille.
"If I go in and sit for two hours it gets stiff like anybody else," he said. "I haven't had to ice it down after a game yet. I just go out, walk home and do whatever. It's been great."
We'll see Tim at halfback in the two-tight package Alabama employs in short yardage. But with the freshman back-ups looking more likely than not to play, Tim's prospects of more carries at halfback might be limited to the goal line situations. In the end, it's probably for a good reason.
"That would be wonderful (if I was at halfback more)," he said. "I don't know what they're going to do yet. They're really waiting on Glen. They know I know both positions.
"I think they're trying to get it so just in case one of those scenarios happen like last year – God forbid that happen – they have a guy ready. So I think they're like ‘Tim know it. In case the worse possible thing happens we've got to have these other guys ready to get some reps."
