I think you got that backwards. McCarthy let Rodgers do whatever he wants. He certainly wasn't an incredible coach, but not the worst you can do.
Biscuit, what you have to understand is that the Pack have a new GM/HC combo. These guys weren't here in 2014. You are arguing they are giving up on Rodgers too early. You could be right. They have evaluated their roster and made their picks accordingly. I don't think they had a stellar draft myself, but when you saw how they got absolutely dismantled in the postseason, it's hard to argue Tee Higgins is going to make or break them next season, and they took Love to secure a successor.
Should they have drafted a receiver in the 4th? Probably. Do I think Gabe Davis on the Packers really makes a difference? No. You can get receivers who contribute at that level day one off the scrap heap.
