In hindsight, Turner did the best he could with the pile of shit that was handed to him throughout the years- Grossman, Orton, Griese, Hester, Benson.... at least he put up a couple respectable years.
Martz and tice had much more to work with and achieved far less.
Turner is also the most cursed OC/QB coach in the league... the grossman-orton era, Jay in his absolute worst season, a year as WR coach in indy... pretty good gig... till he makes QB coach in indy with painter/orlovsky/collins.... then on to tampa and Josh freeman and his old buddy dan orlovsky.
Hard to really diagnose his skill as a coach given the garbage he has had to deal with. he just gets an "incomplete" in my book.
