Wait... do you actually think Peluso would have been the difference in that game? And on top of that you think he should be playing AHEAD of Ehlers, Burmi and Thorburn? I think we have bigger problems to worry about.
We are 5th worst in GA, we have the 2nd worst powerplay, we have the 4th worst penalty kill and people are complaining about 4th line players? If we look at the Jets, more depth would definitely help. However, who plays on the powerplay our top end guys, who plays on the penalty kill, Wheeler, Ladd, Stafford, mostly our top end guys, and as for GA, the 4th line rarely plays close to 10mins a night. So how can you blame the Jets current problem to 4th line players.
Whether it's coaching or the players, right now Wheeler and Schief have been our only good top 6 forwards, because Little's been up and down this season, Ladd's been just awful, Perrault is good but belongs a third line for a playoff team, as well as Stafford.
Edit: We are also 4th worst in faceoff %, another factor that I think gets overlooked.
