A hard question to answer that I won't avoid.
First of all, they are two of the elite players and small forwards in the Class of 2014.
If I was coaching a team, I would take Johnson, an Arizona signee, based on his versatility, a facet of the game that I put a lot of stock into. Johnson is competitive and close to being a complete player, as he can score from deep, in the mid-range and also has a paint game. I like his versatility to handle the ball well enough in the backcourt and to push it on the fast break. He is a power driver who can finish through contact and take on defenders at the rim.
Johnson continues to score in a variety of ways and will be a mismatch as smaller defenders will struggle with his power and strength and bigger players will have a tough time with his speed, skill and mobility.
Oubre, a Kansas signee, has an explosive vertical and is one of the best finishers in the class.
I believe both will be very good on the defensive end. Johnson could defend small forwards and power forwards with his chiseled frame. Oubre will be great on perimeter defense guarding the ball, contesting jumpers and covering ground. When it comes to rebounding, both can and will work on the glass.
They are both stud freshmen who will impact their respective teams next year.
