#2 Much like Otis, Keith Lee too may be getting tutored about working safely
As great as Keith Lee is in the ring, he is a beast of a man, and not everyone that he faces may be similarly sized. The safety of one's opponent is of paramount importance especially when you're a big man. We know that Otis was sent to the WWE Performance Center to work in a safer manner, and the same may hold true for Keith Lee as well.
Sean Ross Sapp revealed on Fightful Select how Otis is generally well-liked backstage but a few spots had caught the attention of those backstage in recent months. While there is no heat with regard to Otis with regard to in-ring safety, the company just wants to plug all the loopholes and ensure that the man hones his skills until he is refined. Such may be true for Keith Lee too.
Neil Peart of Rush, considered to be the greatest drummer in history, took lessons at the height of his popularity, and so there's nothing shameful about honing your ability.
