Cardale attempted 270 pass attempts his entire college career.
In comparison:
Russell Wilson - 1,489
Dak Prescott - 1,169
Wentz - 612
Luck - 1,064
Cam - 280*** Cam would be an exception in this case due to raw talent.
Kirk Cousins - 1128
Winston - 851
Mariotta - 1,167
Bortles - 891
Carr - 1,630
I just tried looking at some of the younger QB's around the league since today's college to NFL transition is a bit different from the one Brady had. As you can see, only Cam Newton came out of college with similar attempts as Cardale, and those two players aren't in the same league. Cardale has a long way to go to learn how to read defenses, work on technique, and just learn about the game of football.
