What to do about Sammy Watkins?

Of course I draft Sammy Watkins days before he is traded to the Rams. Not sure how I feel about this. I feel like this decreases his value because now Jared Goff is throwing him the ball and he is also now in a tougher division for wide receivers.

I drafted him in a dynasty league as my 4th round pick and thought he was a steal, because normally he goes in the early second round in dynasty drafts. Well, at least before he was traded.

Anyway, do you think I should keep him and see how he does or trade him before the season starts?
