Many Celtics fans' gripe with Green was that he was inconsistent (of which I would argue he was consistently inconsistent
) and had those nights where he scored 50+ against the Heat and then he would go on a string of scoring something like 9, 12, 5 points over three of the next five.
Similarly, about a month ago I read how apparently one of his teammates (not named) had soured on Green in Memphis. Possibly called him out but I don't recall the entire report. At the time Green was playing poorly (a la Boston) and it got to the point where he and Courtney Lee were supposedly on the trading block.
More recently however, Green has had several 20+ scoring nights and appears to be in favor with Memphis.
What you really want to look at when comparing Green to Gallo is how consistently Gallo is putting up those 16+ points. Is it every night, more often than not? That's what we want. Someone who can be counted on for 15+ points a game.
For comparison's sake, look at AB. Shot the 3 horribly in January -- shooting what, 10% at one point? -- but we're one week into February and he's bounced back. That inconsistency however could have hurt the Celtics more in January. Thankfully it didn't.
