Michael Thomas is all any team really needs at wide receiver.
Throw a couple of guys out there next to him, and you have a proficient passing offense. There is no hyperbole in this statement. The Saints proved it last year.
So, yeah, adding some guys to the position this offseason was a priority, but only because it is ridiculous to force yourself to rely so heavily on one player, not because Thomas can't handle the weight.
New Orleans already took a big step forward by signing Emmanuel Sanders, but the depth chart behind him is still a little thin. Tre'Quan Smith is in what should be a make-or-break year, and everyone else is unproven. Adding a third receiver to the offense wouldn't be a bad idea if things align during the draft.
To get a better idea of what can get accomplished at this position, I ran a draft simulation on FanSpeak.com and selected a wide receiver in each round. We will do this for other positions of need throughout the next week, but first here is what happened at wide receiver.
