It's a little different, but for the sake of illustration, I grew up in the northern suburbs of Chicago and never particularly wanted to go to the state school. I followed Illini football and hoops, but as a kid I was a bigger fan of Michigan football and UCLA basketball - Illinois was probably my #3 or #4 team. I thought that staying in-state sounded incredibly boring. I wanted to get the heck away from home and explore new horizons. I was 100% positive that I would move to NYC, LA, or maybe Miami as an adult - just had no home state pride whatsoever.
Long story short, I eventually made the practical decision to go to Illinois (top academics + in-state tuition) instead of USC or Ohio State (both of which I was considerably more excited about in a lot of ways). Never regretted it for a minute after I stepped on campus; best years of my life were in Champaign. From the moment I started school, I was a diehard Illini fan and have been now for 17 years. Settled down in Chicago, etc. If I'd been a 4-star HS basketball player, though, there's about a 1% chance I'd have gone to UI. Obviously, with Tim's connection to the program there are tons of variables at play, but I wouldn't be surprised if he found the expectations suffocating at times; growing up in Champaign and being a 2x legacy could cut both ways.
I'll be fine with whatever he decides, as long as he stays out of the B1G and doesn't go anywhere near Travis Ford.
