As Notts never lost to the Stags home or away in the days when it really mattered to me, I don't have any strong feelings of dislike for them and wouldn't mind seeing them go up.
They probably would struggle to stay up though, something they haven't managed to do at that level since the season we won our first Wembley play off in 1989/90. They would almost certainly be among the bottom third in terms of support at that level. 12 clubs have averaged over 8k in tier 3 this season.
