I think as long as cooks injury is 1 or 2 weeks at most you should hold still. Cook is honestly double djs points every week so far, and its not like you are desperate at wr. Thielen and brown should be your bonafide wr starters every week unless you have a bye. If i'm you at 4-1 I believe I can withstand a week or 2 without cook. I don't really want to be trotting out carson and dj as my starting rbs every week for the rest of the season. Gibson has shown promise but that offensive line is gross, moss is a backup, dernest is a backup who won't be relevant in 4-5 weeks. I think if you want to get out of cooks situation aim higher than dj and boyd.
