Blocking the nuts (JT) and the other nuts (78), we have to play it this way.
In his eyes, we only have 22 strong value combos here. We probably have a few more because surely you play Q6/Q7/K6/K7 the same. So we have values and we need bluffs so throw all of our blocker hands in there and we likely have close to the right ratio of bluff:value making this a fantastically played hand.
As I alluded to above, this is a spot where your range is more important than having T7hh here. That's the GTO way of looking at things, right? All of this assuming he plays in a GTO way, of course.
