Cooks and Fuller, while better than Hurns is not even an average NFL WR corp. For the record I would take Cooks over Hurns too but that isn't saying much. He is not a top talent - I would take our top 3 plus Cedric Wilson over Cooks , so he would be a 4th at best but more than likely a 5th WR here - that's the top talent Watson was throwing to last year.
And yes Watson does take a lot of sacks because his WR can't get open. in the first 5 games last year, Dak was sacked around 10 or 11 times - threw like 100 picks and had 400 fumbles or pretty close

and Watson was sacked like 16 or 17 times in those first 5 games, so while our OL was not great, it wasn't as bad as Texans OL. We were still averaging 100 yards a game rushing even with all the turn overs and shootouts we were in the first 5 weeks.
