A few things people need to understand:

Giallanzo was looking at eight-to-ten years via his recommended plea agreement. So he got more than that, but those were simply advisory recommendations. He also has to give over a huge forfeiture and is being forced to sell that house. Giallanzo was looking at far more time than that had he gone to trial and lost.

Giallanzo's indictment charged him as being the head of a 19-year-long racketeering conspiracy that controlled one of the largest recorded loanshark books in recent times, alongside gambling, drug dealing, and extortion. TThe racketeering conspiracy also involved the murder conspiracy and attempted murder of a rival drug dealer. The crimes also alleged that he ran his operation and continued to become rich during a seven-year stint for extortion he served from 2006-2013. So again, Giallanzo's sentence was stiff compared to his plea agreement, but not out-of-the-ballpark insane. Giallanzo knew the sentence recommendations were advisory when he took the deal and he knew the judge Dora Irizarry hated his guts. It was a gamble, which he lost.
