I think the point was to make Garza the starter and bring in Spencer as insurance in case Garza failed. Garza knew the offense and how Olin set the protection. With vitually no offseason for another player to learn, it was a great move as the Bears were desparate to solidify the position. Why else do you think they wanted to WAY overpay, an over the hill, Kruetz? That is one move I'll give Angelo credit for. It may seem pointless now, due to Garza exceeding expectations at center. He's actually better at center than guard and was an upgrade over Olin. Good for Garza, as it gave him a nice extension and prolonged his carreer. Spencer can still be the center of the future as he learns his craft from Garza.
