I know where you are coming from but the club has to weigh up what he would bring to the first team right now and the players development. When Pearson is back cadden has virtually no chance of playing much more than a handful of minutes a game whereas he would benefit from first team experience elsewhere, the club would benefit long term too. Much the same situation with Craig Moore (although I think long term cadden has a greater chance of making at Motherwell than Moore)
