Hindsight is 20/20 on the first paragraph. Chark and McLaurin were projected as WR3-4 types, and Green was initially expected to miss only 4 weeks.
As for the bolded, nah. As a philosophical matter, I want the best team in weeks 14-16. Weeks 4 to 10 matter much less. Just need the rest of my team to be good enough to get into the playoffs. And if it's not, then DJ Chark or Terry McLaurin weren't going to turn a non-playoff team into a league winner anyway. Trading AJG for a Chark or McLaurin just to squeeze out a little production in the middle of the season is a losing approach (IMO).
