I understand that, but its stupid. You're lumping together ALL of last season, which is bullshit. Please omit the games where Stafford was obviously impacted by his injury, and you can do the same with Romo. In fact, let's just focus on how the two ended the season (last 4-5 games). Considering it was Stafford's first full season, it doesn't make sense to evaluate his current status based on how he started the season. His end, which includes significant development due to his youth, is much more applicable in this conversation. Stafford was a different QB by the end of the season, and its reasonable to assume that this improved play was due to progression and development, rather than simply a hot streak.
Therefore, if you would like to properly compare the CURRENT talents of each player, please compare the way these two QBs ended the season, and try and argue for Romo. All you get is completion percentage.
Last 4 games for Stafford: 1664 yds, 15 tds, 4 ints, 64 completion %, 8.76 YPA
Last 4 FULL games for Romo: 1158 yds, 10 tds, 1 int, 72 completion %, 8.27 YPA
You really wanna take completion % over everything else? I'm taking Stafford any day of the week
