I could ask you why other teams have lost more of their top players and you couldn't answer it. It's attributed to bad luck. Btw, it's well documented that Belichick has a tough training camp. However he had to tone it down after the new CBA because he used to have two a days.
The one thing I'd look into if they haven't done so are the type of kleet they are wearing. However, I'm sure they have done this. Nine percent time knee injures occur without any contact at all. Young was practicing on his own, Flacco was lifting in his house, Dixon was practicing on his own, etc etc etc. But we should continue to blame Harbaugh, because it has to be his fault.
The Ravens have not lead the league in injuries in 2014-15-16 and this year although we have more injuries than all the teams, we haven't lost more impact players than other teams. Is it Hugh Jacksons fault that the Browns lost 4 or 5 qbs to injury last year,
Was it Harbaughs fault when we didn't lead the league in IRd players and were closer to the bottom as well?
