Many people post questions here asking about their chances in court. No one online can validly predict what the future holds. The subject penalties may be based on a myriad of reasons. Many factors such as age, prosecutor discretion, what judge you have, whether witnesses are credible all matter and that makes it near impossible to say how much time "does he get".
Check with a KS lawyer in your locale to discuss more of the details.
Good luck to you.

I see many questions on avvo in which people want to do what is going to happen to them because of such and such an offense or parole violation. In truth no one except your lawyer can even give you an approximate answer to that question because it depends on so many variables: your state’s laws and procedures, your criminal history if any, whether there are any sentencing enhancements, whether your state has diversion programs for your offense. These kinds of questions really require that you contact a local lawyer and even then they can only give you a range.
