Looking at their career stats, interestingly both Hall and Romney have faced a similar number of 3rd and 4+ situations. When Hall is in the game, the cliche of not getting behind the chains that applies to option teams applies. When Hall is forced to throw, e.g., on 3rd and 4 or longer, he stuggles, whereas Romney performs pretty well. I think Hall is a good QB, but there's a lot more pressure for the offense to stay on schedule than when Romney's in the game.

Passing on 3rd and 4+ (career)

Hall: 18 of 34, 233 yards, 2 TD, 2 int, 118.2 PER, 10 first downs

Romney: 24 of 35, 306 yards, 0 TD, 1 int, 136.3 PER, 17 first downs

Rushing on 3rd and 4+ (career)

Hall: 10 attempts for 15 yards, 0 TD, 3 first downs

Romney: 7 attempts for -21 yards, 0 TD, 3 first downs

First down percentage on 3rd and 4+ (career)

Hall: 13 of 44 = 29.5%

Romney: 20 of 42 = 47.6%
