True Dez is better than Djax but no one is going to burn you deep like djax can on your roster. So you rather have Williams than Garcon right now. Beasley over Crowder and Butler over Doctson. Wow.
Terrance Williams could be argued to have equal if not better stats than DJax over the last two years. I say last two because that is how long DJax has been on the Skins. DJax has about 200 more yards in two seasons and 1 less TD.
Williams is on par with either Garcon or DJax. Which that right there is your problem. You have no legit #1 WR. Doctson might turn into that, but I wouldn't count on it because 1) he is a rookie and 2) he has done exactly "jack" and "shit" in the NFL.
