The versatile Grosz, who has played tight end and linebacker for SJM, is now looking like he'll end up as a defensive end.
"I just made it back from Notre Dame and it was great. I learned a lot and the last day, Coach (Jappy) Oliver pulled out the top four defensive lineman and I was one of them. That was out of around 50 so it was nice. And it looked like my hard work is getting noticed. I am getting this defensive line thing down."
Prior to that came camps at three in-state schools, all who he's got strong interest in.
"Stanford has always been on the radar and I've always loved Stanford and have built my passion for the school. That's always been a top interest. UCLA has come on and Cal is another," said Grosz. "All three of those schools seem like they're very open to other defensive linemen right now. Most of the coaches have said "you're a great athlete, we'll stay in touch"
Aside from the Golden State programs, the Ivy League is also scoping out Grosz.
"Yale and Cornell are two Ivy League schools that have shown interest," said Grosz. "San Diego State seems like a school that could come through."
Then of course, is the hometown Bulldogs.
"I've always loved Fresno State," said Grosz. "I go to all the games and have been in the stadium many times. But I have heard nothing from them. I think there was a call in February, where my coach called their coach. I've been sending them my packets and my film."
While Grosz has been playing linebacker and tight end during his prep career, he acknowledges that his future appears to be at defensive end.
"Cal, UCLA and Stanford all had me playing defensive end," said Grosz. "But I want to be noticed for more than a defensive end. I want to be a guy who can go in and increase his speed, play any kind of special teams."
Grosz is an excellent student, carrying a 4.1 and he's scored a 1490 on the SAT and a 22 on the ACT.
