My company is coming to an end, and while I wait for a couple interviews I have, I've decided to do the crossword from the Express each day.  But today, I need a little help.
 
 I've filled in a good bit, but one of the answers (or what should be an answer based on other answers filling the letters in) doesn't make sense to me.  I think it might be sports-related, which is my weakest subject. 
 
 Anyway, the clue is "Packs down firmly," and the answer seems to be "Tamps."  I don't get it.  Anyone?
