All the Rudy Gay hate is a little outdated.
Once upon a time, Gay averaged about 19/6, with low efficiency and a giant contract.
Today, he's been around 20 ppg with TS% of 56 for the last 3 years. He gets to the line (80%+) and is a decent outside shooter (~35%+). He has a reasonable contract. He legitimately plays two positions as a 3/ stretch 4 in today's game.
He's not an All-Star, but he's a darn good player. He's never played in a winning environment or for a good coach.
Would I pay a ton for him? No. But getting Rudy Gay cheap beats the heck out of overpaying for e.g. Horford.
29 year-old guys who can score 20ppg with decent efficiency, play two positions, and have reasonable contracts don't grow on trees...
