With Liles, I think it comes down to how ready Gardiner is to take his place and at this point, Gardiner is nowhere near ready to do that IMO.
This is not a question of depth, it's a question of development and or talent. If you remove Liles from this team, as we've seen over the past little bit, you notice the hole it creates. I've seen more posts than I can count about how we miss Liles.
Now maybe it will come down to how much that would cost us, which is probably an important question right now, because we do have players that need to be re-upped, specifically Grabovski, so maybe the first question should be what we're going to do with him?
I like Grabo and I know a lot of others do as well. Burkes is going to have to make some very difficult decisions in the next couple weeks, but it's starting to look to me that he needs to send a few contracts out the door, for one coming back and try to save a bit of cap space for next year. I haven't done the specific number crunching, but we have too many bodies going forward, with kids looking ready to come up and some bigger holes to fill also.
I'd try to keep Liles and move out some forwards and a defensman for a better forward coming back that fills a need.
