Put your left foot in, put your left foot out

• Regarding that campaign, it will be curious to see how much emphasis the coaches will be putting in that effort. 

I will be curious, not it will be curious. Or it will be interesting.

OK, technically you can use “curious” to mean “interesting” or “unusual” (he used a curious term); but who actually says it will be curious to see? I guess sportswriters, mostly.

And this I’m sure of:

• They’ll put emphasis on that effort, not in.

You can put emphasis on an effort, or put energy into an effort, or demonstrate any number of qualities in an effort; but you can’t put emphasis in an effort.

Not in American English, anyway. (Brits, kindly advise.)
