I do, yes. From the interviews I've seen, his attitude definitely isn't favorable. I can't say 100% positively that he's a jerk because I don't know him in person and none of us do, but I definitely think he's cocky and arrogant...he even said at the U.S. Open he "wanted to be more cocky and arrogant".
Everyone will have a different opinion of Tiger...I've never met him in person but I've been a huge fan since 2000 and I've followed him as closely as possible since then. I know his personality and think he's a nice guy. Obviously he made huge mistakes in his personal life, but the way he's dealt with those mistakes are even more evidence in his favor. He's pledged to be a better person and father every single day and from what I've seen, he's succeeding in that.
Oh, and I'll mention Bubba Watson as a possible jerk as well:
