[1] Distin was the better player in the early part of the season. How many more times do you have to watch the 6-3 against Chelsea? This is the same Distin whom Jagielka has played alongside for five plus years now, with some of our best-ever defensive stats coming in that time period. How on earth could Jags feel "uncomfortable" playing alongside him?[1] Jagileka played badly when he had a terrible player alongside him.
Hows that hard to understand, if you dont feel comfortable with the player alongside you, your gonna struggle to perform, coupled with the liability in goal behind him and it made his performances suffer.
[2] He was selected player of the season by ALL his peers and the fanbase as a whole.
[3] Hes a truly remarkable defender and will only get better with age.
Hes got probably 2 full seasons at the very top, hes a fit lad and he appears to have a lifestyle that will only prolong his career, we should look to phase him out of the first team around the middle of the 2017/18 season when its likely we will see a SLIGHT drop in his overall performance.
[2] Who were the realistic alternatives? We hardly had many stand-out performers. I would have given it to Lukaku myself. I'd be interested to know if anyone else was close in the voting among the players.
[3] He didn't get better this year, did he.
I'm not saying your wrong re your last paragraph. It's just a matter of odds. You are gambling on the most optimistic conclusion of his career, whereas I am taking a more cautious approach. If the right player is available at the right price this summer, would you really refuse to sign that player?
