That simplification isn't quite right. There's a bias toward pressing because if once you account for all (a) opponent turnovers (b) opponent easy shots and (c) Tennessee easy shots off backcourt pressure, the remainder, (d) has more Tennessee possessions than opponent possessions.
I'll give an example. Let's say our opponent takes 10 shots that we'd categorize as "easy", making 8 of them. Let's say Tennessee forces 20 opponent turnovers. And let's say that 3 of those turnovers are steals which turn into easy points.
In that particular sample, the score is
Tennessee - 6
Opponent - 16
So -10? But consider (d), which is every other possession besides the 33 that I described in (a)(b)(c). 30 of those possessions are opponent possessions (20 turnovers + 10 high success transition shots) and only 3 are Tennessee possessions (the 3 scoop-n-scores)
If we make the assumptions that both teams are going to score 0.9 points per possession, and take into account that Tennessee has 77 possessions remaining, but Opponent has only 50 possessions remaining, then we find that in sample (d) alone, the score is
Tennessee (0.9 * 77) = 69
Opponent (0.9 * 50) = 45
Which would give a final score of
Tennessee - 75
Opponent - 61
The numbers here are just made up on the spot, and could certainly be scrutinized to be more realistic, but they serve to make the point that many people wil tend to overstate the pain of giving up an "easy 2" while understating the reward of generating an extra turnover, which are approximately equal in relativ value. There's different ways to frame it, but all that matters is that it's the foundation of a successful gameplan, and it's why we don't lose by much very often, and why we win by a heck of a lot a decent bit.
