And when Arizona offered in May, it was a huge relief for the 5-10, 195-pounder.
"It was really exciting to get my first offer," said Mashack. "It was a big weight lifted off my shoulders. I'd been working hard all offseason, working with B2G and training three times a day so it was a huge relief."
For it to come from a BCS conference was an even bigger deal.
"It was big because the Pac-12 is a big conference," said Mashack. "On the West Coast, everyone wants to play in the Pac-12. It was extremely exciting and lets me know I can play for one of the most exciting conferences in the country."
More offers could be coming too for Mashack.
"A couple schools, like Colorado, want me to go to their camp, Arizona State, they're looking at my film, Nevada, they want me to come out to their camp and they might offer me, and then I'm talking to USC and UCLA a little bit. Hopefully those schools could end up offering me," said Mashack.
Mashack has already camped at USC and UCLA's 1-Day Camps, and will be back in Westwood on Friday.
"I did really well at USC and I talked to Coach (Clancy) Pendergast and he said he really liked me," said Mashack. "I went to UCLA's camp and did my thing and played really well and Coach Meat (Demetrice Martin), said he wanted me to go the Elite Camp on Friday so hopefully I get a chance to show them again."
Mashack said he's not in any rush to see his recruitment end.
"It's still really early, so I'm still doing my research on a lot of schools," said Mashack. "I kind of want to see what comes to me and look at my options and by that time during the season I should have a good idea."
Mashack also plans to take all five trips.
"I will be taking all of my official visits, most definitely," said Mashack.
