He's done none of those things. If anything, it's precisely the opposite. He's conservative and patient to a fault. He probably gives a little too much rope to coaches. He uses a longer timeline than just about any other GM to manage the cap. He defers football matters to the coaches.
His approach only works if you have a very strong, detail oriented coach like Payton. Allen is really a poor fit, and I think where Loomis falls short is evaluating personnel. He whiffed with the Allen hire, and he was really fortunate with the Payton hire.
