On the final play, I don't see where anyone thinks that NW doubled Tyler. They were man to man and Jbo set a screen for Tyler, Tyler's man fought over the top of the screen which made Jbo's defender hesitate and allow the space for Jbo to get the shot off. Why the guy from NW was guarding Tyler out at the 3 point line with 3 seconds left is the mistake because he never should have been caught on top of the screener there.
To finish my point, which is a lot of the same as revkev is saying, is that our team is definitely better with Tyler Cook on it. There is no way we are close to as good or better without him on the court. His athleticism and physicality is by far the best of anyone on this team, and he is constantly active as a post player, rebounder, screener, etc. He is a nightmare to guard.
However, as one poster said that you want a post player to receive the ball and take a moment to assess the defense, if the double is coming and where it is coming from, and he is absolutely right. However, I don't think Tyler is there yet to make positive plays from that position. He is best at receiving the entry pass deep in the post and immediately making a move. Within 5 feet of the rim, he is over 70% from the field, and this does not include the foul trouble that he puts on the opponents, so his win rate here is amazing. Within 12 feet in the lane, he is right at 50%, still a great win rate. However, outside of the lane beyond 5 feet, which includes both wings and beyond 12 feet in the lane, his field goal percentage is less than 20% and I am sure that he doesn't draw as many fouls out there on the wings. What we saw in the NW game in the second half was a lot of feeding him from the wing, where he was 12-15 feet from the rim with his back to the basket. I don't think this is his game right now. A player like Lebron that can both do damage from this area and assess where the open man is when the double comes, it makes sense.
When we get the flowing action where we swing the ball on the perimeter and feed Tyler as he comes across the lane is when really good things happen for us. But the stagnant, lets slowly dribble the ball up the court, get in a half court set and then softly pass the ball to a stationary Tyler and let the offense run through him isnt how we are going to win games.
