Why can't both be true?
Analytics can suggest its a great move for 2-3 years with diminishing returns past that time. But what player like Tuch can you acquire for a 3rd rounder, and/or on FA?
I mean look at their cap situation. 2030-31 is looking like the great exodus. If they don't do much with that group, it's rebuild time like it or not, because none of those contracts are going to look good in 4 years
So in short, the Caps might not be looking past that 3-4 years mark anyway because they see the wall coming.
