It's not like having too many guards or too many bigs.
Not in today's league.
Look -- SG, SF, PF. That's three positions on the floor. In small ball lineups, you can add the C position as well.
That's at least 144 minutes between those 3 spots, plus whatever minutes you want to allocate for super small lineups where a 3/4 plays at the 5.
Let's say you have 5 guys who all could play 20+ mpg. For example -- Hayward, George, Crowder, Brown, and Tatum.
You could play them 32, 32, 28, 28, and 24 minutes per game.
32 or 28 might be a little bit on the low side for some of those guys, but at least during the regular season that's not a bad thing.
So, I don't really understand this preoccupation with the "logjam" the Celts might have on the wing. Especially if they don't sign Hayward or trade for George.
YOU CAN NEVER HAVE ENOUGH VERSATILE, TALENTED WING PLAYERS IN TODAY'S NBA.
Full stop.
That maxim is right up there with "don't overpay for pure centers" and "the most important kind of player in the NBA to have is an elite pick and roll shot creator."
