 Adele won a Grammy for 19 in 2010 so that was probably her first big exposure in the US and Chasing Pavements had become a 'hit' (using the term loosely) after 19 came out so it was just a matter of increased exposure following 19 and 21 having better promotion in the US. Rolling In the Deep might not have been a hit yet, but it was already her biggest single in the States when 21 came out.
