Totally agree with you. Lleyton's commentary is very insightful and in-depth, but he just talks a little too much. The match that Lleyton was commentating on turned out to be a complete analytical talk show because he wouldn't stop blabbing on about things in high detail.
Would've liked Lleyton to give Bruce and Jim a turn at the mic for once, and at least showed more courtesy to what's currently going on in the match. I remember Wawrinka hit an absolute forehand screamer down the line at 170mk/h, but instead of acknowledging the shot, Lleyton kept going on about tactics and other off topic things.
Tonight's match between Tomic and Nadal is going to be interesting with Lleyton in the commentary booth. There has been a bit of a feud between Lleyton and Tomic in the past, so I wonder how Lleyton is going to approach this match. Will he be supportive or critical of Tomic? Not sure, but we'll wait and see.
