Perhaps it depends how regularly you play? I used to be an infrequent BB player and a very infrequent WHFB player. Because of this, catastrophes that befell my team / army tended to seem worse, because it might be weeks or months before I got to play again. I now play BB weekly; and although I hardly ever play WHFB these days, if I do it will be 2 smaller battles in one day, rather than 1 big battle. This makes all the 'bad stuff' seem less important, as there will be imminent opportunities for some better luck!
Also, if my opponent is stalling I see it as a chance to make some memorable heroic plays! On several occasions I have grabbed an unlikely draw or win when my opponent was stalling in order to beat up my team and leave me no time to score. Indeed, just the other week my opponent's Norse team were leading 1-0 against my Humans with a few turns to go. My opponent decided to cage the ball and pound on my few remaining players. I had a prone Human Catcher with Block who got up, dodged away from the Snow Troll, dodged into the cage and 2 dice-against Blitzed the Norse Thrower - who was knocked down and seriously injured - and then dodged away from the only other adjacent Norse player. In my opponent's turn he got a few players next to my Catcher and Blitzed - Skulls and Pushes, no re-rolls left! In my turn, the same Catcher dodged away from the Norse, scooped up the ball in 2 tackle zones, legged it and made 2 Go For It rolls to put him out of range of all the Norse team. My last turn, he runs in for the equalising TD

I don't really protect my players, regardless of their skills / SPPs - I figure that if they are on the pitch they should be trying their damn hardest to inconvenience the opponent, even if massively outnumbered! If an expensive / skilled player dies then so what? It just creates a gap on the roster for perhaps an even BETTER player to develop
