The offense was bad, I will agree. The entire offense wasn't dropping balls though and that is what we are talking about. Dez had 6, Butler had 3, TWill had 2, Witten, Williams, Beasley, Zeke, and Noah Brown each had 1.
Here is a number of dropped balls since Dez has been on team. First number is team total and then Dez in parenthesis.
2010 - 25 drops (Dez 2)
2011 - 26 drops (Dez 2)
2012 - 33 drops (Dez 9)
2013 - 25 drops (Dez 6)
2014 - 10 drops (Dez 5)
2015 - 19 drops (Dez 5)
2016 - 8 drops (Dez 1)
2017 - 15 drops (Dez 6)
I'm not going to blame Dak for the drops unless you can show me where these dropped passes started when Dak took over and somehow became a QB issue.
