Don't be fooled by the number. Prosecutors often use those numbers to scare defendants and reporters don't really know any better. That's the maximum sentence. In the real world, maximum sentences are extremely rare, especially for a first conviction, especially for "white collar" crimes such as those alleged here. He most likely will be sentenced to probation, possibly with some incarceration on the front end. All of it depends on a lot of things; his sentence may be made worse because of his high profile and the desire to appear non-biased and/or tough on crime, but nothing like 17 years. A lot will also depend on where he scores out under federal sentencing guidelines, although those aren't typically as strictly followed as the ones here in Florida are.
