It's as much about mentality as it is about attitude.
Winners have a narcissistic streak and believe that they're going to triumph. Losers doubt their own ability and question whether or not, they have what it takes.
As Connery said in The Rock, 'Losers always whine about doing their best. Winners go home and fvck the prom queen'.
Winning breeds winning and at the moment, this team team simply don't have the mental strength to see out the games on a consistent basis.
Today, we went a goal behind, pulled it back to 2-1, and then dropped 2 points from a winning position.
As I type, the mentally challengeds went a goal behind, pulled it back to 2-1, and then ......
Watch how that one ends and then compare the difference.
As it currently stands, we simply don't have the mental fortitude to see things over the line, and own the right to call ourselves Champions.
