Nobody said that he is worth 11M dude. He had a down year and I wouldn't be surprised if he had a jump in points next season at all. He gets a 2nd minimum in return based solely on the impact and presence that he brings to teams with decent numbers too (for his contract it's definitely below what he should be putting up, but the points he does get plus his impact/presence gives you at least a 2nd round pick)

1) Pesce is coming off of a career-low year and is still being given a 1M raise plus term so the contract is fair
2) Stamkos will be 35 this off-season and he's not going to get a raise; maybe a slight one if any like 8.5M or 9M which the Leafs can still afford. Plus it is his home town which could make a tiny difference
3) Tavares is still a capable player and only has 1 year left on his deal. Trading him to Chicago will gain assets not lose them. He also provides Chicago with something they desperately need in a proven veteran leader. They also have more than enough cap space which wouldn't impact them whatsoever so no need to add a pick to move him. If it was a team struggling with the cap i would 100% agree with you
