For some reason people just think Drew's mistakes are worse than another QB doing the same thing. Interceptions are costly. They are never pretty in general. He has only 7, most are not really his fault.
Drew's 7 interceptions:
1) @SF - returned for a TD (mistake #1 outcome: Win)
2) @SF - after SF fumble, a great defensive play on sideline
3) @OAK - Hail Mary
4) NYG - Hit as he was releasing pass for would-be Glenn TD
5) @SEA - Great play after ball deflected on would-be Glenn TD
6) @SEA - Bad pass with 11 seconds left (Mistake #2 outcome L)
7) @PHI - Bad pass during would-be sack (Mistake #3 outcome W)
So he really only had 3 bad mistakes resulting in 1 loss (and there is no guarantee Dallas would have won in OT vs Seattle). He could easily have 2 TDs instead of 2 of those, and be 16 TD 5 INT.
