In 2010 the Nevada Wolfpack ended up #11 in the nation going 13-1. Starting QB Colin Kaepernick (2nd round 49ers), TE Virgil Green (7th round Broncos), and RB Via Taua (FA Seahawks) all graduated leaving Matthews as the only proven play maker heading into last year. All Matthews did was improve his numbers from:
2010: 56 catches, 879 yards, 5 TD
2011: 91 catches, 1364 yards, 8 TD
Pretty impressive considering how much talent around him graduated from the program.
Also, played big in big games against the Wolfpacks best opponents. In 2010 the Wolfpack's toughest opponents were Cal, Boise St. and Boston College (Bowl Game):
vs. Cal: 3 catches, 83 yards, 1 TD
vs. Boise St.: 10 catches, 172 yards, 1 TD, 1 rush, 44 yards, 1 TD
vs. Boston College: 7 catches, 86 yards, 1 TD, also returned punt for TD
In 2011 the Wolfpack's toughest opponents were Oregon, Texas Tech, Boise St.:
vs. Oregon: 8 catches, 100 yards
vs. Texas Tech: 5 catches, 107 yards, 1 TD
vs. Boise St.: 4 catches, 84 yards, 1 TD
Also had a 10 catch, 220 yards, 1 TD game vs. UNLV and 12 catch, 205 yards, 1 TD game against Utah St.
After watching him play during college and in preseason it seems clear to me Rishard Matthews is legit.
