Michigan has not had a 1,000+ yard receiver on the football team since Mario Manningham back in 2007. That year there were only 3 receivers with a receiving average over 11 ypc: Manningham (16.3) Adrian Arrington (13.2) and Carson Butler (12.3). The rest who caught passes had way less than 10 yards per catch.
This year, no one UM receiver is even remotely close to 1,000+ yards. The top of the list is RS Fr. Roy Roundtree with 318 yards. Virtually all of Michigan's receivers with 8 catches or more this season have YPC in double digits: Roundtree (13.8), Mathews (12.4), Odoms (12.4), Hemingway (17.5), Stonum (15.8), Koger (13.8).
I was looking back at some of RR's receiver stats at Tulane, Clemson and West Virginia. When he took the job at WVU in 2001 he had already coached three previous circa 1,000 yard receivers:
WR PJ Franklin, Tulane, 1,216 yrds, 10 TDs (1998)
SB Jujuan Dawson, Tulane, 1,030 yrds, 12 TDs (1998)
WR Rod Gardner, Clemson, 1,084 yrds, 4 TDs (1999)
WR Rod Gardner, Clemson, 956 yrds, 6 TDs (2000)
At WVU RR didn't get a 1,000 yard receiver until year 3, when QB Rasheed Marshall was in his 2nd year at QB:
WR Chris Henry, WVU, 1,006 yrds, 10 TDs (2003)
Rodriguez never had another 1,000+ receiver since 2003, though Chris Henry game close again in 2004 (872 yrds, 12 TDs) and so did Darius Reynaud back in 2007 (735 yds, 12 TDs).
Michigan's roster for 2010 is so WR/SB-rich for 2010, it's almost sickening. With two experienced sophomore QBs, the passing game should improve somewhat in 2010, as should the receiver play. Of the 8 receivers with 10 catches or more in 2009, 5 will return to the lineup in 2010. Michigan's youth and experience level at running back in 2010 might also prompt a little more throwing.
If there is a candidate for achieving the 1,000 yard mark in 2010 would have to be Roundtree, because in just 5 games he has as many receptions (23) as Greg Mathews, more yardage than any other receiver and more TD catches (3). Roundtree doesn't have blazing speed, but he's been an excellent possession receiver and his YPC are impressive for a RS freshman.
