My take on it is the players have until January to prove themselves and the manager has until May. Caldwell's biggest problem will be he won't be able to replace all the dead wood in January. His task is to get us clear of the play off spot well before the season finishes and to have concrete signs that we will be at least heading for the proper play offs next season.
The lesson from the the two "2 footed tackles" is if you're on the receiving end don't try to win the ball, you might make contact with your assailant. Just jump up out the way and writhe about and the perpetrator will be sent off.
On a week where two other players had their red cards rescinded and Thistle were denied a stonewall penalty. the spotlight is on bad decisions against Rangers. I think Pedro knows exactly what he's doing and don't fancy any team getting a 50-50 decision v Rangers for a while
How many different centre halves has he played alongside?
He is still only 20 of course he'll make mistakes,but he's still at least 6 years from his peak.
