Short answer - No, not after you stir the crap out of it to mash in.
Well, at this point I usually add the disclaimer. "This is what I do. It works for me. Your process may vary".
I have a 10 gallon RIMS system, so I am heating the mash liquid directly, but the theory is the same. When you fly sparge you don't really recirculate, you just use the pump to redirect the runoff to the kettle (slowly). When I batch sparge, I drain the mash tun into the kettle, which compacts the grain bed a little, add my first sparge volume, usually 4.5-5.5 gallons, give it a stir, put it back on recirculate for 10 minutes till the wort clears, drain again, add my second rinse (again 4.5-5.5 gallons), no stir here, recirc for another 10 minutes, drain to collect 15 gallons pre boil. I usually get 82% efficiency and the gravity of the final runnings is never less that 1.015 at 168F so no worries with tannins.
