2021 Michigan football season preview: Offensive line

Continuing our positional season preview series, we take a look at Michigan's offensive line, previewing the position battles, depth chart, strengths, weaknesses, questions and making a bold prediction on the Wolverines' front for the 2021 season.We begin by taking a look at position battles, as Michigan returns seven players who started up front in 2021, leading to technically three position battles. We assess the competition level at each spot, how the Wolverines could move layers around to truly come up with a 'best five,' and why Michigan may wait longer than usual to decide its starting five up front.We then turn to the group's strengths, looking at the line's depth, size and potential ability to move the line of scrimmage more this year than last season. We also look at weaknesses up front, including some pass protection concerns and a lack of experience and proven production. We then offer our biggest questions about the group, then make prediction for the line's outlook this fall.
