Apart from your condescending remarks that "he would be a great encyclopedia or vacuum cleaner salesman," there's absolutely nothing wrong with the qualities you listed.
Every player is paid to be where they are. There is nothing wrong with or negative about his enthusiasm and "lobbying for a job." For crying out loud, that is what all backups do!
I'm not advocating for his return to the Saints. As another member posted, "That ship has sailed."
I just strongly disagree with your description of Jameis as an insincere player and individual. He was nothing less than exemplary as a teammate and player for the Saints and your comments speaking so dismissively of his character are uncalled for IMHO.
Perhaps you should read your signature line again:
"Do the right thing because it's the right thing to do...even when no one is watching"
