I've never seen anywhere that suggested that Taman had great connections, great ability to scout talent, ability to draft, ability to bring in new talent to replace expensive declining talent, absolutely nothing.
I've only read and seen him make trades with known names and sign guys based on some players recommending friends. It's ok to admit we hired a mediocre/crap GM... it's not like we need to defend the choices of Reinbold/Kelly/Burke and even Mack to a certain extent. It happens but to be in loser denial is fooling no one. Taman was in way over his head as a GM and I'm sure whatever he is doing now is much more perfectly suited for his level of talent.
This is not a knock on the guys personality or who he is as a person. In today's world the level of professionalism is ten fold more critical in the CFL and he simply wasn't on that level.
Murphy was never a GM but he was scouted and "desired" because he did have a great ability to recruit and find talent. It's not something that a quick napkin or google search of cfl rosters can do. As a person he clearly is an a-hole and sometimes you can have all the talent in the world but if you have a crap personality (see A. Brown in the NFL) you simply won't find a long term home.
