No, of course not. He is just too big to have the quickness that I would like to see in a slot. Anyway, I guess we can say that you and others don't see a problem with a big slot and I just think we already have a big guy (TE) in the middle and that a little guy will be able to create some havoc. We'll see how it plays out. For the other part, I was wondering if when Davante takes a step back but is still wide; if they consider him to have played the slot (for statistics sake) on that play. Looking forward to the draft and then the season. I think we are a lot better! And am very interested to see what Gute does in the draft. I am hoping for an OT early. If one of the three are available.
If your issue is with the idea of a "big slot" in general, then you're going to have to deal with the reality of players like Keenan Allen, Larry Fitzgerald, Cooper Kupp, Michael Thomas, Mohamed Sanu, Juju Smith-Schuster, Tyler Boyd, etc. It's a pretty commonly used concept in the league today.
One reason why I think Moore's athletic profile fits inside is his quickness. He put up a 6.56 three cone and a 4.04 short shuttle at combine, which are excellent marks regardless of how big you are, let alone for a 6'3" receiver. However, all I'm advocating for is that they try him there in camp. If he hasn't gotten his hands figured out, then he isn't a fit anywhere.
I am sure that any reputable statistics outlet is only counting a player as putting in a snap in the slot if he is literally in the slot. They understand that the Z, or flanker position it not the same thing as the slot position.
I will say that you're right about Graham-- playing in the slot seems like it's about the only fit for him in Petals' offense. He cannot block well enough to play in line. However, he's also not a threat after the catch, which makes him less than ideal in the slot as well.
They really shouldn't be basing any plans around Graham anyways. He's gone after this year. Shoot, I'm still hoping he gets traded during the draft.
