All of the clue answers are

numbers, from 1 to 15

Specifically,

• Something many association football and ice hockey goalkeepers choose to wear = 1, as their jersey number
• Taking the Browns to the Super Bowl is doing this? = Defecating, aka "going #2"
• Chelsea F.C.'s most recent kit sponsor = Three
• It's represented by a red flag with a white cross = 4
• This is often given up high = 5
• Three of these together is a bad sign = 6
• River in North Yorkshire = 7
• Figure often seen tied in knots = 8
• More of these means something is finer = 9
• It features two Elizabeths, for the time being = £10, with pictures of Queen Elizabeth II (deceased, but it seems that the Bank of England hasn't gotten around to issuing new notes with King Charles III) and Jane Austen character Elizabeth Bennet.
• She got her name from a mark on her arm = Eleven (Stranger Things character)
• American slang term for the police = 12
• Broadway musical in which Ariana Grande made her debut = 13
• Nickname for the third group of astronauts selected by NASA = 14
• Song from Taylor Swift's second album = 15

The 16th cell should be

empty

because according to your question title,

the grid is a 15 Puzzle, and needs one unoccupied position so that tiles can be slid around.

• BTW, how do you do list markup inside spoiler markup? Sep 9 at 0:40
• I don't believe bullets work in spoilers, but I've separated your answers onto different lines so they're a bit easier to read. hopefully that helps. in the future you can do this by adding two spaces at the end of each line Sep 9 at 0:55
• nice job working your way through the answers, btw! enjoy your green check Sep 9 at 0:56
