I can say that significant injuries, acl's etc happen. Every team gets significant injuries.
Every team does get injuries, although last year didn't get hardly any major injuries, we got teams when they were on a bad slope and got the lucky bounces we aren't getting this season.
We need more depth at every position. We (in my opinion) need our GM to stop trading down for quantity and start taking the best players at the positions we are slotted.
Ted has done a good job building a core, but its time to get some depth with QUALITY players and hit on some great players. If not, then when injuries happen we'll continue too see crap games like we saw today.
