I'm too lazy to find it, but there was a DesNews article a few days ago where Roderick was quoted as basically saying he laughs when he hears fans say that.
We've really only seen Romney with a broken toe (2019) and in garbage time (2020), so I don't think we as fans know what he is. But we should keep in mind that Hall's brother was a really quick RB with nifty feet, while Romney's brother is our deep threat at WR. If these guys can throw and are similar athletes to their brothers, that should make you smile!
Roderick was quoted in that article as saying that we will run the same O as last year cuz all our QBs have the arm strength to make all the throws ZW made and the mobility to do the same sprintouts and RO plays. With that, I suspect that Hall and Romney are pretty comparable in mobility and arm strength. What a luxury to have 2 guys who are that interchangeable!
