The Bears have a proud tradition at middle linebacker, with all-time greats like Dick Butkus, Mike Singletary, and Brian Urlacher at the top of the list. But the transition from Urlacher to the next generation hasn’t been seamless.

For now, a pair of candidates are vying for the starting job, and according to the officially unofficial depth chart, D.J. Williams and Jon Bostic are neck and neck as co-starters.

Williams, who signed as a free agent in 2013 and re-signed after the season, started last year until he tore a pectoral muscle in Week Six. Bostic took over, and the 50th overall pick in the 2013 draft struggled enough to prompt the Bears to consider sliding him to the outside for 2014.
