There are 193 safeties in the NFL, only three of whom weigh 230 pounds or more ... that's just 1.6% ... the heaviest safety in the NFL (Kam Chancellor from the Seattle Seahawks) weighs 232 pounds, while the lightest weighs 187 pounds.
Grant, being just 18 years old and never having been in a college strength and conditioning program, will likely put on 15 to 25 pounds before he graduates ... and it is very unlikely that there will ever be a 250-pound safety in the NFL.
Of the 193 safeties in the NFL, 51 weigh 200 pounds or less (26.4%), and only 21 weigh 220 pounds or more (10.9%).
The average weight of all NFL safeties is 207.2 pounds (in other words, 23 pounds less than Curtis Grant weighs as a high school player).

Troy Polamalu: 207
