I thinks it's going to take a while to focus on his game without his Dad's support. I mean think about it, his Dad was so integrated into every facet of his golfing career that for Tiger it would seem impossible to seperate the two. I remember watching one of those recent Tiger specials on the GC...when he was talking about how important his Dad still is at this point even though he can't make it to all the tourneys. He would be struggling that day and later call his Dad for input (since he was watching him play on TV), and his Dad would tell him what he saw Tiger doing differently than before. Tiger would take the advice, put it to use the next day and turn things around. His Dad knew his son's tendecies and swing, and Tiger used this as support. It wouldn't surprise me if it takes him a while to get back to the level before his dad died.
