Did I do the right thing?

My oldest sons coach of 4 years (football) is my younger sons coach this year for flag football.

He asked us if our oldest was going to play tackle this season?
I replied I don't think so. He doesn't want to.
My son was a bit embarrassed- he had to then admit he wasn't sure if he wanted to play or not and explain why lol
He was a bit upset with me because I didn't cover up for him lol

But he'll be 11 soon he needs to own up and admit to making his own decisions.
Obviously I want him to play if not tackle football- any other sport of his choosing...
