Transfers is now part of College Football and Basketball. You almost have to predict there will be a number of players leaving your roster every year. Spring Practice is clearly one of those hot spots on whether a player will be starting in the Fall or a back-up.
The latest rumor is Giles Jackson maybe headed to another program. The speedster was used primarily in a returner role last year and I'm sure was looking for more reps at slot WR this season. This also could be the classic "home sick" situation as Giles is from California.
If Giles does leave Ann Arbor is total WR stats over 2 seasons would be 24 total catches for 309 yards.
