No way does the NHL go to a wider surface as it would mean removal of some high price seats.
Glass seats would be much better as would the first few rows if people's feets were where the boards turn into plexiglass.
The Garden is way too shallow in the lower bowl the first 7-8 rows are effectively obstructed.
5 rows of good seats > 8 rows of obstructed ones.
I would only sit in rows 3-6 behind the goal at the Garden I wouldn't want those seats on the sides but somewhere like Centre Bell which is steep gets good literally the 4th or 5th row.
2 rows of seats would add about 8 feet of ice and I think it would be worth it.
Im a PC fan in college and Schneider Arena where they play is undersized like the old Garden and the team is fantastic and watching them play road games this weekend I noticed right away that the extra room made the team a lot better than they were at home and the undersized home sheet probably hurts them.
