Training camp is still a couple of months away, but there is reason to be very optimistic about the 2010 NFL season. Since the 2009 season ended in January, the Ravens have made enough upgrades to become serious contenders.

The Ravens have improved in the areas where they had major weaknesses, from the addition of several wide receivers to getting younger on defense to finding another pass rusher. http://www.baltimoresun.com/sports/ravens/bs-sp-preston-draft-0425-20100424,0,5039289.column
