You might have seen Dak performing a similar drill before the SNF game last night.

What does Dak have in common with Jimmy? He works with John Beck, a former NFL QB who coaches at @train3DQB with Tom House. pic.twitter.com/sk0yycECCk

Dak Prescott told me a few weeks ago he spent the offseason working with QB coach John Beck on "oblique flexibility," among other things -- which has increased his throwing velocity and distance.
He just threw that pass 68 yards in the air... 😳@NBCDFW @1053thefan
