Al McCoy still calling games, sharp as ever... but with a bit more of a homer bias (which I appreciated) into his late 80s was remarkable. The guy was calling live action, second by second, player by player, calling out names of guys that were not even born when he was retirement age... that is amazing stuff.
When we brought Marv Albert's brother in to announce for a while... I think his name was Zoran Alberts, that was brutal stuff, he was calling games for TV, didn't even NEED to be on the ball, calling every moment, yet he seemingly got players names wrong, ref calls wrong, just totally unable to keep pace with the game, hop in the car and tune into the broadcast and Al in 2015 was as crisp as could be.
In the 90s all the road games were simulcast, radio and TV, with Al and Cotton (outside of Cotton briefly coaching again), and on the cable side for home games we had Gary Bender, who I was fine with but my dad couldn't stand. For a while there, when my dad was in town (he was an airline pilot and gone a lot) we'd have the TV muted, watching the game and listening to the radio for non-simulcast home games, the radio was a good 5-10 seconds ahead of the cable broadcast. It bugged me at the time, having the action spoiled... but now I am sure I'd love it.
