Simmonds is the wildcard, and we wont know what the deal is until 2018. If he can be retained at a reasonable number (under $6M) for a reasonable term (4 years), then I think we resign him. More term or more money required, then he will need to be traded. Cant have him into his 35+ y/o seasons, nor can we go with too much money, especially with the G & Jake contracts in place.
But I just can't see him signing a 4-year deal, and I don't think he should - he would be getting bad advice from his agent to do so. It's his last big contract and he should be looking to set himself up with the longest deal possible. If the best situation for him is Philadelphia - and it probably is - he could play with the dollar amounts some to make it work with our cap and dissuade Hexy from needing to move him (or thinking he needs to), but I think he will absolutely ask for 6 years. I wouldn't blame him for a second - that's what he should be asking for - but I also would move him before we got to that point. I've traded him on these boards about 100 times, but I'd still be happy if he stayed and signed, because he rules, obviously.
