^^not certain what you saw (or didn’t see actually) that makes you believe he was slightly above average.
Week 1 first half he was 12/18 for 160+, 2 TDs and 0 INT. His passer rating was 128.6. He only threw 6 passes in second have because he didn’t need to pass. Packers dominated and run game did scoring. As an aside, Love was 8/9 for 128 and a TD between the numbers with a 155.8 passer rating, highest in the NFL.
Week 2 he was 19/31 for 292, 2 TDs, 0 INT, and a passer rating of 113.9. Again , Packers jumped out quick in first half and mostly controlled the game. As an aside, Love was 14/17 for 178 and a TD outside the numbers with a 129.9 passer rating.
35/53 for 480, 4 TD, 0 INT and a passer rating of 120.0 thru 2 games (1 1/2) seems to be a little better than slightly average.
