There is no way the quarterback for NU is currently on the roster for next year. Unless Sims has a miraculous turnaround, he will be replaced.
Rhule isn't an idiot. He needed to bring someone in with the QB room NU had. He had no idea what he would get out of Thompson or if he could even play. Then Thompson didn't want to compete, so he left.
My guess is that it will be the same next year—if Sims doesn't want to compete, he will leave.
Additionally, it's important to acknowledge that the options in the transfer portal were limited, and NU might not have been at the top of their list for many quality quarterbacks. Talented QBs often choose destinations with higher potential for success, such as better offensive lines, receivers, and a winning track record. Unfortunately, NU hasn't been able to offer these advantages in recent years, making it less attractive to prospective quarterbacks.
