Disagree with Bleacher Report

I don't think it has anything to do with speed, the kid is quick. What I heard Mayock say was he lacked physicality. Now that becomes an issue more for wide right/left WRs more so than slot because you have many teams that play press. You get a physical, strong corner who is decent to good at press, it screws the entire route up.

Here is why, all you tape watchers. Notice how much time the average QB has to make a decision and throw the ball. Most have no more than 3-4 seconds to make a play. Otherwise, they'll be on their butt with a 250-320 lb dude on top of them. Most analysts say Brees makes decisions even faster than that, which he tends to do.

But that isn't just Brees elite ability to find the open man that makes that happen so quickly. It has a TON to do with the offensive scheme that allows players to be open. But another important part is the ability of that player to GET OPEN. Now if Stills is fast but hasn't shined in physical battles, I can see where analysts may think he is better suited for the slot. In the slot you have a LB or a safety who most of the time, with not press because they will get burnt bad. (FYI - this is why many analysts like Vaccaro, he can press and play similar to a CB) When lined up against the #1 or #2 CB, you many times will get pressed, especially with blitz packages. If that stops or slows the pattern by 1-2 seconds, now Brees literally has 1, maybe 2 seconds to completely read the field and find a re-routed open WR.

If looking at that scenario from a statistics standpoint. It is much more likely the play does not go the way we would like. A WR must be able to get off the pressing CB almost instantly and into their route. Otherwise the play becomes improv and that is when bad things tend to happen.
