(CNN) -- Jerry Sandusky's lawyers are seeking a new trial for their client, according to court documents filed Thursday in Centre County court in Pennsylvania.
The former Penn State assistant football coach was sentenced to no less than 30 years and no more than 60 years in prison after being convicted in June of sexually abusing 10 boys during a 15-year period.
In addition to requesting a new trial, lawyers for the 68-year-old former defensive coordinator filed a motion Thursday to have the sentence reconsidered.
The lawyers argue that there was insufficient evidence to convict Sandusky, and that the court didn't allow them enough time to prepare for trial. They also argue, among other things, that certain counts should have been dismissed on the grounds that they were too general and non-specific and, as a result, prevented Sandusky from preparing an adequate defense.
After the sentencing, defense attorney Joe Amendola said that, if the team had been allowed more time to prepare for the trial, Sandusky would have been acquitted.
At his sentencing, Sandusky called the outcome of the trial "the worst loss of my life."
"I will cherish the opportunity to be a candle for others," he said, adding that "somehow, some way, something good will come out of this."
The scandal, which erupted nearly a year ago, led to the firing of head football coach Joe Paterno and the ouster of the university's longtime president, Graham Spanier. Paterno died in January.
Jurors determined in June that Sandusky, who retired from Penn State in 1999, used his access to university facilities and his foundation for underprivileged youths to sexually abuse the boys. During the trial, the 23-year-old man identified as Victim No. 4 testified that he was 13 when Sandusky sexually abused him in a university shower.
