I'm both not surprised and surprised by the reactions here. All seem to be stemming from the lack of a timeout.
I'm not surprised people are upset about the lack of a timeout, that seems to be a common gripe. Personally, I've long been a fan of no timeouts in situations like that. Don't give the defense a chance to set up. Offense usually has the upper hand in these situations, don't give that up. I realize I tend to be in the minority with this opinion though.
What I'm surprised about is people's expectation of the play that would be called coming out of a timeout here. I feel like any play coming out of a timeout here is going to be a Tatum iso where he holds the ball running a lot of time off the clock, it's not going to be some quick shot or complex play.
The guy you want to have the ball has the ball where you want him to have the ball against a bench guy who was only playing because Jimmy Butler was out (he played 0, 5, 5 minutes in his last 3 games). You want to call a timeout and give the D a chance to deny Tatum the ball?
When I was watching the game, I felt pretty good at the time. Tatum with the ball, ~15 seconds left, this is about as good a set up as you could hope for given the situation.
Also saving the timeout gave the C's a decent look for a final shot. They were able to call 2 timeouts with 0.6 left, one to advance the ball, and one after they couldn't inbound the first time. Had Joe called a timeout earlier, they wouldn't have been able to do that, and the C's don't even get a shot off. Of course the obvious counter is C's wouldn't have been down with 0.6 left if Joe called a timeout on the previous play, but that still could have ended with a miss or steal by the Heat, putting the C's in the same situation but with only one timeout.
Not calling a timeout worked pretty well for Ime vs the Nets in Game 1. Someone will say this is a more experienced lineup, true, I have no counter. I remember watching this live and thought Stevens would have called a timeout soon as the play started to breakdown when Jaylen drove and got cut off at the baseline.
Not calling a timeout worked pretty well for Joe vs the Lakers. Was this not the same situation, down 2, ~20 seconds left, give the ball to Tatum and let him do his thing? Similar oddball lineup too (actually the Tatum/White/Pritchard/GWill/RWill lineup has played together more than the Tatum/Smart/Brown/GWill/Kornet lineup).
Here Ime called a timeout to set up a Tatum iso against the reigning DPOY. But Joe already had a Tatum iso, against a worse defender, an undrafted guy who was only playing because Jimmy Butler was out.
This is Brad calling a timeout to advance the ball, with the play being just give the ball to Tatum. No special play drawn up (unless you consider the Hayward pick special). The play was give the ball to Tatum.
I have my doubts a timeout would have changed things last night. A good chance the play would be very similar to what we got (Tatum iso, Rob pick, Pritchard/White/Grant spacing). Tatum with the ball is a good place to be closing out games.
