Some of the largest sections at MSG are at center ice in the 200 level. These sections contain up to 25 rows of seating. For a Rangers game, it is better to sit in a lower row in a corner or end section than Row 15 or higher at center ice. You won't lose much in terms of your view of the ice, and navigating the stairs with multiple beers will be much easier.
Otherwise, sitting in the first ten rows at center ice gives you a wonderful view of both ends of the ice and of the penalty box and players benches. Sit in 223-225 to look at the player benches or on the opposite side to see the penalty boxes. Row 1 in all sections come with an HDTV screen at your feet (except Section 224).
