What don't you like about McKinney??
Could see Mauldin being an Elephant OLB... would be another versatile piece to the defensive front.
There are some other LB's I like... I'd be okay with Anthony in the 1st round... As for CB, Shaw has more talent than a 4th round pick, but he might drop b/c of the off field stuff.
Grayson has a chance to be a very good QB... I wouldn't normally advocate taking a QB that early with a franchise QB under center, but Rodgers won't play forever, and Grayson could develop into either a tradable piece, or a season saver should Rodgers go down.
I really like Covington... he has a lot of ability, an Aaron Donald type, he's just been plagued by injuries - certainly worth a flyer in the 5th.
Our main weaknesses are ILB and CB... the draft I threw out there addresses those weaknesses I think.
