Carr was injured in game #7 last year at IND. These are his numbers from the first six games:
114/195 59% Completions 1421 yards 5 TDs 7 INTs
Barring injuries, over a full year that had him on pace for...
304/520 59% Completions 3789 yards 13 TDs 18 INTs
Now the TD/INT ratio is pretty bad, but nearly 60% completion percentage and 3789 yards are not bad numbers at all.
