My feeling on this is that Marvin Jones could start declining at any moment or he could play at a relatively high level for another 2 or 3 years. I definitely wouldn't trade for him but I would pick him up as a FA IF he can still be a deep threat and he doesn't cost too much.
I'm not sure what to do with Kupp. I just feel like he's not going to hold up. But he is outstanding at times and always very good. His RAC is super. I like Woods. I feel like he is replaceable but why would I want to replace him. Consummate Pro... Just like Marvin Jones Jr.
