Love is not explosive and def a below the rim player. People are forever overblowing athleticism. If there is one thing to offset athleticism it is skill. And Frank has more skill than any 7fter in recent memory.
He averaged 8 boards and game and 2 blocks. He will be average at worst in that department. rebounding is a lot to do with hustle and toughness. Frank doesnt appear to be that soft or lazy. Franks problem is he needs to add some more weight and know how to use / anchor his body and not be backed down so easily.
