I think we have succeeded ( so far knock on wood) on keeping the sheer number of injuries down this year, but the ones we've had have been key. It's easy to forget we lost Miles Fox before the season even started, who could've helped at DT. Despite Masterson's not being the fastest guy, he was a key lose on defense. Strnad of course was a huge loss on defense, really the glue of the defense. Now, we lose Washington (at least for multiple games) and Sage for the rest of the season, maybe the best WR combo in the league other than Clemson. Short of losing Newman, Herron, Boogie or Bassey, we've lost some of the most key players we could lose.
And we rarely come away from Clemson without some serious injuries.
