These are my defenders stats:

9 goals in 40 games - DL
4 goals in 40 games - DC (1)
4 goals in 40 games - DC (2)
4 goals in 40 games - DC (3)
7 goals in 37 games - DR

So yea all together this season I noticed an improvement comparing with the last season for my defenders but nothing special, I think these are pretty decent stats.
