Kittle has 9 targets through 2 games and LaPorta has 11 targets through 2 games. However Goff has 70 passing attempts vs Purdy’s 54. So Kittle has 16.6% target share vs a 15.7% for LaPorta. They both have an 82% snap percentage and both are around 10 yards per catch. They are essentially the same player so far this season. Start whatever one you think has the best matchup. Based on this, I wouldn’t blame you for sticking with Kittle, considering he had 10 TDs last year and isn’t a rookie.
