Michigan really seems to be lacking elite talent at RB. They've went to bat at the RB position this class.
Zach Charbonnet (6'2, 215) out of California picked Michigan over USC and UCLA. 247 is bullish on Charbonnet- they rate him as the #40 player overall in the country and #4 RB- and the 247 West coast analysts Greg Biggins and Brandon Huffman both said he's the top RB out West and that they both have him in contention for FIVE STARZ.
Eric Gray (5'10, 190) out of Tennessee picked Michigan over Penn State and Alabama. 247 is bullish on him as well, they have him rated as the #87 player overall and the #1 All-Purpose RB. Gray lit it up at The Opening and saw his rankings rise. He's rushed for 5,366 yards and scored 90 touchdowns combined in his sophomore and jr seasons of high school football. He was Mr. Football in the state of Tennessee as a junior.
Giles Jackson (5'9, 175) out of California picked Michigan over USC and Oregon. 247 ranks him as the #213 player overall and the #3 All-Purpose back in the country. He really blew up at The Opening, having one of the top 5 SPARQ scores there after reeling off a 4.43 in the 40 (the 6th fastest time at the event) and a 3.85 in the shuttle (the top shuttle time there) and a 38.5" vertical. He was listed by 247 on their All-Opening Team at slot receiver over 5* WR Garrett Wilson- and was listed as one of the top performers overall that week. He started at receiver as a sophomore in HS and caught 42 passes for 847 yards and 13 TD's, then as a RB as a junior when he rushed for 1,586 yards and 22 TD's- so he's got experience playing both positions. Dynamic athlete that can play both spots and return kicks as well.
Now all they need is to develop an offensive line and hire an offensive co-ordinator who has a clue.
