I think it's fine to be both happy with the end result and also frustrated with how we got there. If you're up by 29 with less than 20 minutes of game time left... The outcome of the game should never ever be in doubt.
the difference to me vs something like 2015 tcu, where we blew a huge lead and lost, is that yesterday we won. yeah, it was frustrating and anal clenching to almost blow a huge lead and fall on our faces yet again, but, in 5 years, i won't give a crap how we won yesterday. i'll only remember that we did and savor that memory.
