Aguilar has absolutely nothing to lose this year. Milton was a bit cautious at times because he wanted clean tape for scouts, and Nico absolutely wanted to protect his "two seasons and straight to a 1st round pick" status (which we now know isn't happening). Aguilar isn't on any NFL radars but could make some noise with a big season here, but that requires absolutely ripping it when asked to.
I think he's going to throw more picks than we have seen under Heupel thus far and likely will again for a long time, but he'll also throw 25+ TDs.
