Beat me to it :).
Most of the 2 ndary played both ways in HS. Redmond and Siegenthaler were primarily RBs. McCloskey also. All the others were primarily DBs. Ripanti was an A-S FB.
Off season developementis limited in the summer to physical regime. Coaches are allowed to conduct skills mini camp programs for players. LU does.
While I get it would be ego boosting to get 3* recruits at every position,that a recruit isn’t one is not predictive of how good a player is.
I have looked at all the video of KW that I could find. I am at a loss to see what some others claim. He is very athletuc and finishes his tackles. He may not be a sub 4.5 guy but he is not slow by any definition of that term. A great prospect at SS.
