The Bears desire to upgrade the offensive line isn't a secret, and they're expected to be in play for the most prominent one - Jake Long. A four-time Pro Bowl left tackle and the No. 1 pick in 2008, Long is coming off a rough season, and his market is unclear. He was placed on the IR for the final four games with a torn triceps, and he missed the final two games in 2011 after a torn biceps muscle. The Bears have at least expressed an interest in checking on the status of some prominent free-agent guards and tackles but what they're willing to spend on the positions or particular player is the multi-million question. There has been speculation that Long is looking to make an average of $11-$12 million a year, but it would be hard to imagine the Bears paying that. Long was considered one of the truly elite left tackles earlier in his career, but his play suffered in the last two seasons, when he was sidelined with injuries. According to Pro Football Focus, Long was ranked 47th out of 75 tackles last season. In 2011, he was 21st but second in 2010 and second in 2009.
