The answers to this flat are based on a seven-letter word:

1 2 3 4 5 6 7

When our team is 2 3, we cheer

And 1 2 3 4 5 6 7 them. 

When they lose,

All they get is boos.

We're not good 1 4 5 6 7s, I fear.

 

Answer:

 

When our team is UP, we cheer

And SUPPORT them.

When they lose,

All they get is boos. 

We're not good SPORTs, I fear.
