Jacksonville had 4 more drives than the Rams, which is why they have better offensive stats

The rams offense did not get a first drive (ST scores), the teams then alternate possession until the blocked punt. Thus Jacksonville gets 2 possessions to end the half and then another to start the second half. If you don't count the knell down, the rams offense had 10 possessions and Jacksonville had 14.
This is something to note when commenting on the rams offense.
