I wouldn't panic or take the hit personally mate, Kane and Toney are two of the three top scoring forwards in the game - think you've more then a punchers chance of them matching Watkins or Isak with a - 4 - not worth the hit in my opinion. You can also play two up top and five in the middle easily.
I just sold Watkins incidentally on my WC - he's a form pick, but how will he match up with other like Martial in 34 or Isak in 36 - i think the time to have had Watkins might have been a few weeks ago - he still might hold his own but ill play the % on those having more DGW games matching or bettering (but then im chasing).
If i was taking a hit, it would be for someone with a double as you have a chance of covering the spread on the hit with the extra game - so the hit would only cost you 2 points at a minimum - wouldn't be Watkins it would be Isak or Martial. Toney 33 - Martial 34 - Isak 36 over the next weeks may be viable, gets you 6 games - over say Watkins 4 and - 4 for the hit.
I've gone ahead and WC'd - looks like I'm married to the BB strategy.
