St John's absolutely has more talent and more depth than Seton Hall. The two secrets to Seton Hall's success are that Kadary Richmond makes everything happen for them and Holloway does a brilliant job of using the other (mediocre) pieces he has to full advantage (i.e. plays to their strengths, hides their weaknesses, something our staff could maybe learn from) and getting his team to play like junkyard dogs who haven't eaten in a week at all times.
It's a must-win game for St. John's. Richmond will do what he does, unless Pitino remembers that Glen Taylor is a guy who makes your team better and plays him to defend Richmond (instead of what I think he WILL do, which is deploy Luis for that which will result in him fouling out). The key is that SJU has to want the game as much as Seton Hall does (because they want EVERY game) and the ball has to move to the best matchup instead of forcing certain ones. Oh, and feed Soriano, they have nobody who can contend with him if St John's decides to focus on feeding the post.
