In no way does the Right to a Speedy Trial force plea bargains. Further, most plea bargains result in the defendant pleading to a single count of the highest-level offense, resulting in the same sentence that would have resulted if he'd been convicted of all charges at trial. The only way they go to a lesser crime is if the case is weak, and then it's because the case is weak, not that they have to go to trial in a hurry. In serious cases it is common for the defense to waive the speedy trial requirement, giving the state more time to prepare its case. You've done a disservice to your community by providing false information about criminal justice.
