Sorry to be so direct... In my opinion, if you feel there is or might be a problem with the way the team performs then I suggested that you try to fix it. Send an email, a letter, talk to the players or hold up a nice sign for the coaching staff to see what it is you would like done differently.
I didn't ask you to shut up and not wonder. In fact my suggestion is the opposite, I suggested (an still do) that you help fix what you perceive as a problem.
If you don't want to do that then you could repost something like
'geez, it sure looked like the returners muffed nearly every kick return they had in the scrimmage. Does anyone know what they do in practice to address this?'

Or-
'I sure hope we have better special teams play than we did last year'

I apologize for suggesting that you take action instead of just stating a perceived problem.
