Spieth will pass Mickelson in majors. I’ll take bets on it … if I’m alive to pay
Love Spieth but he's a self-saboteur. He has remarkable touch when he's free wheeling and guys like Justin Thomas have said that in practice rounds Spieth is like watching an amazing pool trick shot artist as he's constantly doing incredible things... I think that's the way he practices. But when he tries to drill down in crunch time and it's no longer a free wheeling good time, well that's when he keeps making those big mistakes. Catch-22 - he's great but only when he is playing with house money. I don't think he passes Phil as he'd have to win 4 more. I think the only Major he wins again is the Masters, maybe a couple times but that's it.
I look at it as there are two kinds of great players, those that you wait to see do something spectacular in the biggest moments and those that you wait to see do something awful when it matters the most as they're snake bit, Spieth is definitely the latter.
