Trotter will be as good as his pass protection...
First 3 games, he was sacked 3 times and hurried 7 times
45-71-2-605yds-6tds (157.2 rating) - Would be 21st nationally
Last 2 games, he was sacked 7 time and hurried 17 times
28-51-3-290yds-3tds (110.3 rating) - Would be 100th nationally
The same would likely hold true for Kiehl Frazier or Clint Moseley. Frazier would likely have better success than Trotter under extreme pressure but Frazier doesn't reach his full potential until the OL does.
