Michigan has to find an answer at both right and left tackle next season. If the offense wants to improve, this isn't an option. As a result, U-M coach Jim Harbaugh is looking anywhere he can for help, including the graduate transfer route. Harbaugh and members of his staff visited with Rice graduate transfer offensive tackle Calvin Anderson on Monday. Anderson, a 6-foot-5, 300-pounder from Houston who was an honorable mention tackle in Conference USA in 2016 and 2017.
