Bush is gunshy about his knee… its tge real reason most guys take two years to get back from that injury… nobody trusts a joint that gave out that painfully for a bit…I usually hate to speak in hyperbole ... but in this case I'll make an exception. It doesn't matter how you quantify it, height, weight, era played in ... Bush is playing like he's scared someone is going to take his lunch money. He jogs to contact and tries to arm tackle. He's been slow to react. He's gun shy and has been one of the weakest links of the defense this year. He needs to be replaced next year.
