I really liked TJ. But I agree that QVC Host was not a good fit for him. But that's OK.
I truly think sometimes the wrong job opens you up to the right job. QVC Host is not the be all/end all as a measure of success. TJ never seemed to do any homework as a host for any product. But his innate talent in humor and being extremely likable was still very refreshing.
In his NPR short interview, he says he didn't feel QVC was giving him the opportunities to succeed, so he left. Don't know if that's totally accurate or not. But QVC would have been crazy to give TJ main channel shows, or even more responsibility on QVC 2. He was just not ready and never looked like he would ever be ready.
Hopefully through this experience, he'll do something he loves and excels in it. Possibly acting, motivational speaking, coaching, or a brand rep for exercise equipment or any number of areas. He has a huge personality, and looking at his social media he has a lot of Hollywood connections. He seems like a great guy.
