Randall and Rollins are starting to look like two more high draft picks wasted by TT on his leaky defense. Coupled with letting House and Hayward walk, when they were viable alternatives to Randall and Rollins being selected in the first place, it is looking like TT made some serious errors here (although you must be fair in giving him credit for drafting House & Hayward to begin with).
E. Wolf has had a hand in pro scouting I believe. Cook and Peppers have worked out well. Rumors are around about others that TT just wouldn't spend on.
Finally, I remember when R. Wolf retired. It caught Harlan by surprise, he had no plan in place to replace Wolf, then panicked and we ended up with GM/HC M. Sherman. TT could retire at any time just like R. Wolf did.
So, if Murphy's plan is to promote E. Wolf to GM when TT retires, he may have to push TT aside, or, risk not having either one of them one year from now.
