"I thought I did pretty good. Actually, I just came out from track. I ran in the state track meet last week, so it was kind of a big transfer from track to football.
"But overall I was pretty competitive. A little bit sloppy with the work, but that will all change shortly because our team starts practicing."
The 5'-9" scatback has played on Zuppke Field previously, including a state championship game last fall, but his perspective was different this time.
"I just want to thank God for this commit to Illinois and playing on this field, my future home field. It was great, 'Man, I'm coming here. Look at this big stadium.' I'm a home kid from Peoria, just representing.
"I've camped here a couple times before, but it's a lot different when you have a commitment. This is my home now."
Foster looks thicker, a tribute to his workout regimen. His track times didn't suffer despite increased weight.
"Yeah, I now weigh 190. I've been hitting the weights hard. But I'm still quick, and I'm still trying to knock people over. Usually I drop about 10 pounds during track season. But I was able to keep it on this time."
As a future Illini, Foster is trying to help attact top players to join him. Crete-Monee receiver Laquon Treadwell is one whom Foster has been talking with recently.
"I've talked to Laquon Treadwell a bit. We text every day pretty much, see how he's doing, see how I'm doing, how his family's doing. From the sound of it, Illinois is in his top five. We have a great relationship, and hopefully he'll commit. Me and Aaron Bailey would love to have him."
He is optimistic fellow Peorian Josh Augusta will join him at Illinois as well.
"I talk to Josh Augusta here and there. He had a great state track meet and represented Peoria. Hopefully he comes here."
