This does seem to be becoming the "go to" gripe.
At the 5 minute mark the C's were playing pretty shaky ball for 2 minutes. The lead was 17 and Eddie hit a jumper, that for me, sealed the idea that the starters would have to come back in. I saw sloppy enough play from Lester and co. for a couple of minutes though that I a second of concern (not that we'd lose necessarily, but that we'd have to get some rotation guys back in there). If I'm thinking that, I'm sure Doc is.
If Doc is erring a minute or two on the side of caution, I don't have an issue with it.
