@ChadHarper3794 @JuMosq @packers Alien athlete, with infinitely better blocking ability and higher upside than Ben Simms + possibly available for cheap.

@JuMosq @packers Why? We have Kraft and Musgrave.

Make the call @packers

Cheese curds hate to see the rookies coming

@packers Adrian Amos never gets credit for how good he was his first couple of seasons in GB

@leall_andrea But that's where you are wrong. I am not sure who really. mentored who this past year😂. Thank you for keeping me sane and grounded. Never change!!!

@MMars24_DO Couldn't have done it without your mentorship!! 😊An amazing co-chief and person!

@UPMCPath Thank you for the kind words🥹. I was beyond fortunate to have absolute rockstars and literal energizer bunnies for co-chiefs in @SimmiPatelMD and @leall_andrea that made me look good via association.

A heartfelt thank you to our outgoing Chief Resident, Mason Marshall! His tremendous hard work, patience, and dedication truly made a difference in the program. We are lucky to have you as a #CytoPath fellow in the next academic year!

@SamKhader It is going to be a great year!😎

We are very lucky to have Mason in our fellowship!
