True, but with a slighty different emphasis, which is why 'long adverbs' are not as common mid-sentence. For example, In Charley very often plays football, the adverb very often by position directly modifies the verb plays, placing pimary focus on the action plays, rather than on the event plays football, whereas in Charley plays football very often by position modifies the event plays football.

The dog [quickly [ate [the food]]. Back to our example 'very often', with 'long adverbs' the tendency is to place 'weightier' information at the end of the clause, to make it easier for the listener/reader to process the information. (See also a discussion about frequency adverbs and word order).
