We have nothing but questions marks at TE aside from Keller. Even if Cumberland is healthy, he's still an unknown who has really done nothing besides flash here and there in the pre-season. He's better suited as the #3 TE on the depth chart.
Shiancoe sporting some wear and tear now and prolly doesn't bring anything different to the Jets. Baker looked good last year and good step up as an effective all round TE. Also having Cumberland back if healthy should boost the TE corps.
