I don't know if he can keep up this pace... but I went back and looked at the teams he's faced, and he has faced a much softer schedule than he will the rest of the way...
---------------Comp/Att yds Tds Int
Week 3 (@NWE) 20/28 247 2 2
Week 4 (NYJ) 12/27 128 2 0
Week 5 (JAC) 20/30 220 3 0
Week 7 (@BAL) 29/43 374 4 2
Now here are the numbers for each of those opponents and how they ranked in yds/TDs/Total Fantasy Pts allowed
Most yds allowed per game to QBs
NE: 291.7 (3rd most)
NYJ: 243.3 (11th most)
Jac: 265.1 ( 6th most)
Bal: 214.7 (23rd most)
Most TDs allowed per game to QBs
NE: 2.0 (4th most)
NYJ: 1.7 (12th most)
Jac: 2.3 (2nd most)
Bal: 1.1 (24th most)
Most Fantasy points allowed per game to QBs
NE: 26.83 (3rd most)
NYJ 23.38 (6th most)
Jac: 29.19 (2nd most)
Bal: 17.86 (25 most)
So in conclusion, 3 of the 4 teams he has faced, are 3 of the 6 that allow the most points to QBs. Fitzpatrick also had less yards than the average number of yards that those teams have allowed through 7 games. It is encouraging that he blew the numbers up against Bal which was ranked as 31st is pts allowed before week 7, allowing only 188.2 yds, .7 TDs and 13.57 fantasy pts per game.
Here's how the next opp rank in fantasy pts allowed to QBs over the next weeks:
8: @KC --- 15th
9: vs Chi --- 31st
10: vs Det --- 9th
11: @ Cin --- 22nd
12: vs Pit --- 29th
13: @ Min --- 23rd
14: vs Cle --- 7th
15: @ Mia --- 18th
16: vs NE --- 3rd
so the schedule does get harder for him, so we will see if he can perform just as well vs Chi, Pit, Min, but definately worth starting him vs KC, Det, Cle and NE
