The problem with that group is that all of it is complementary, and none of them are able to elevate the group on their own. DJ Moore is a fine #1, if you have top end talent elsewhere. Cole Kmet is a fine TE, if you have top end talent elsewhere. Swift is an okay RB, you need to surround with top end talent elsewhere.
if every player in the league went into a draft tomorrow, none of the Bears players would be close to selected at the top of their position. It’s all second tier (or lower) guys. That’s fine, if you have an elite QB, but the Bears do not, and probably will not for a couple years. So they have to spread it around to everybody, and to do that you need a hell of a lot more than what they have now.
