Yes there were countless small things we could have cleaned up to win this game, but I do agree with the OP that that Jalen turnover was the biggest blunder that "cost" us the game. Now we all know the catch-22 here is a game is made up of a series of plays and decisions, and its impossible to hinge a loss on a single play. BUT, if you HAD to choose a single play that "cost" the game it would have to be that one. Now all of these little mishaps are all in hindsight, if we tweaked a number of things throughout the entire game we would have won by a few points.
So sad to see us lose this one, we had it in the bag. Ollie needs to do a better job with late close game management plain and simple.
