That would be a pretty big day for Pitta, but not too crazy to rule it out.
Collie had 17 receptions for 241 yards and 2 touchdowns, including 6 receptions for 66 yards in the Super Bowl. Pitta already has 10 receptions for 137 yards and 2 touchdowns.
Comparing regular season stats of these two former Cougars from their Super Bowl seasons is also interesting.
Collie: 2009 - 60 rec. 676 yards 7 TD
Pitta: 2012 - 61 rec. 669 yards 7 TD
If Pitta has 111 yards receiving on 6 receptions in the Super Bowl, then Collie and he will both end up with the exact same combined stats for the regular season and playoffs (77 receptions, 917 yards, 9 TD).
