I don't think the fumbles have anything to do with the lack of carries recently. If that were the case he wouldn't be returning KO's either. IMHO, I think it's one of two things (because I believe HCBD really likes Newsome's skill set), either Newsome is nursing an injury and is playing through it or Newsome's grades are good enough to play, but not where HCBD would like them to be. I'm leaning toward the later. I read an article where HCBD stated that some of the freshmen were adjusting to the balance between college athletics and academics, better then others. He pointed to Johnson as one who was adjusting quite well. Newsome wasn't singled out, but he was mentioned in the same article. If that's the case, it's possible HCBD is sending Newsome a message....get your academics where "I" want them or you'll see the field less. Just my thoughts on the subject, nothing factual.
As much as I like Johnson, he's not a homerun hitter. Newsome can be. I like the future of the position with two guys who can rush for 1000 yards in 2015 (if the OL vastly improves).
