As with all things in WWE, things have to be accountable. Sting comes at a cost, he's on a contract. But with the WCW Icon making just a handful of appearances in 2015, Vince McMahon is likely questioning if he is getting good value on that deal. He did the same with Brock Lesnar, and ended up getting more dates out of Brock. That could now be the same stumbling block with Sting, maybe WWE are pressing for more dates out of him, in order to generate more value for money. God knows they need him, with the roster being so depleted of stars. But maybe Sting isn't playing ball. He's got his comfort level and isn't shifting from it. That could be what all this is about, WWE wanting more dates, but Sting wanting to just do rare appearances.
