I don't think that at all. Kyle hardly played this season due to injury. With him gone, the Bills were forced to run more 3-4 with Dareus at nose. The defense was supposed to be multiple. Some 3-4, some 4-3 and variations of both. Kyle was a key piece and we missed him this year. Not having him, made our defense much more predictable.
That doesn't mean Kyle won't be gone next year though. He isn't getting any younger and I see him much the way I saw Fed Jackson....a great player who is on the down hill side of his career. The Bills may try to find his replacement because of that. This team obviously is productive in a base 4-3 so overhauling now and trying to go 3-4 could be a mistake. We don't want to do away with 4-3 or 3-4. We want to run both.
