a lot of two skill-deficient athletes on the wing in Baxter & George (I'm all for playing both those guys a ton), I'd think Johnson's skillset is the one that sticks out to me as the most needed as the off guard. Followed by Hardy. While we can afford to probably have a 2 who isn't the best defender this year, I think ball handling & the ability to create a shot from the outside & get in the paint & score at the rim will come as a premium. Johnson & Hardy both do all those things clearly better than Knell.
I would see a much better opportunity for Knell if either Johnson or Hardy weren't themselves pretty reliable from deep.
