>The demolition of the Theater at MSG would free up substantial room for the train hub below, which is crowded with structural columns that disrupt the passage of commuters, said Elizabeth Goldstein, the president of the Municipal Art Society, a nonprofit preservation group that was briefed on the plans. The group supported a similar overhaul of the train station in 2014.

>But it would not solve all of the station’s problems, Ms. Goldstein said. The plan doesn’t add train capacity, nor does it address congestion issues on the Seventh Avenue side of the station, where pedestrians exit the subway, she said. Historically, most passengers have entered the station from the east, not the west, though redevelopment of Manhattan’s Far West Side may alter that.

Everyone talks about whether the arena should move but why not just get rid of two Penn Plaza? The office building takes up about a quarter of the block above the station. It's easier to put a value on the cost of buying an office building than the cost of buying the only large arena in Manhattan.

When Vornado wanted the land the governor and mayor supported spending somewhere between $7 billion and $10 billion to eminent domain entire blocks to work around both the MSG arena and 2 Penn Plaza.

If this proposal that can create some light and space on the 8th avenue side by tearing down the theater is not enough and light/space is also ended on the 7th avenue side then just tear down the single building that is on top of the 7th avenue side.
