So obviously, I will take the way Demers, Wingels, and Shep are playing. However, beware that these guys are historically streaky players, all in their contract years.
It will be difficult for DW; these players are all UFA soon, and he cannot offer them a "prove it again" type contract. He might have to pay and accept the risk that these guys might fail. With Wingels and Sheppard, DW will have some leeway in that if Shep wants 2+ and Wingels wants 4+, DW has other options. But Demers is fairly unique; if he comes looking for 4+, DW might have to give it to him.
