Reisner, who had been in constant contact with the Iowa staff, had been hoping for an Iowa offer for several months, and finally received it on Monday night.
"Coach Ferentz called my cell phone," Reisner said. "I was at Benton Community for a basketball game. I knew they were going to call me, they'd told me coach they had a meeting yesterday and they were going to tell me what's going on, so I didn't have to wait any longer.
"I answered the phone and he said, 'This is Coach Ferentz, University of Iowa.' He said, 'How would you like to be an Iowa Hawkeye?' I said, 'I'd be glad to.' He just congratulated me on this honor and I just told him I was shocked."
For many young athletes, waiting so long for an offer would have been discouraging, and some may have even committed elsewhere, but Offensive Line Coach Reese Morgan helped keep Reisner in the loop and positive about his prospects.
"I was talking to Coach Morgan a lot, he was helping me out the whole time," he said. "He kept telling me to be patient. He brought it down to something like track. He said it was like running a mile on the track.
"He said after the football season that we're just halfway there, then after winter break we were almost done. He just told me to be patient, and that every day closer to signing day it was looking better."
The Iowa staff said they had seen qualities similar to former Hawkeye Dallas Clark, who is playing in the Super Bowl on Sunday, particularly Reisner's ball control. That receiving ability helped Reisner catch 48 passes for 678 yards and 12 touchdowns, even while nursing an injury for most of the season.
Having just received his scholarship offer and accepted, Reisner simply had to call someone, right? His parents, his coach, his friends?
"I actually didn't call anybody, I wanted to keep it down," Reisner said. "We had a basketball game, and it was a pretty serious game for our conference lead. If we would have lost this game, we'd have dropped a game back. I didn't really tell anybody.
"I told my dad to call Coach Morgan, he wanted to talk to my dad. I just left it at that until after the game. I told the boys in the locker room, and my dad had told the parents a little bit. The word got around and everybody knew."
Reisner's team won the game by 12 points.
