Ohio St./Mich St. line - help an amateur out

[jameellionaire]

Why is it that, when you go to the betting page, Pinnacle holds the line at -3.5 +111, when the -3 can be had at +100? Is there something can be inferred from the fact that Pinnacle is holding at -3.5?

Of course, just as I say that, they move the line down to -3. Nonetheless, I would appreciate insight as to what it means when a line is being "juiced" like that or whatever it's called.
