The beauty of grad transfers is that you can do both: bring in GTs who are immediately eligible and seasoned enough to play and contribute (the level depends on the players), and still have the scholarships available for 2019.
We need a ton of help on the front line. Not only rebounding help, but scoring help too. Illogomeh and Kene (who may not come back) aren't scorers, and neither is Brown for that matter. If we don't improve our front line, we will really struggle this coming season, no matter how good the young guards are.
Even if Kene comes back, that's only three players, and not very good players, to man the 4 and 5. We need multiple grad transfers who are bigs for 2018-19.
