Tyrus' jumper did improve overall and I'll tell you why.
The 2-17 shooting in the Boston game put him into a huge funk for nearly 3 weeks(almost every game in that stretch was just horrible shooting by Tyrus). Minus those 3 weeks the rest of the season he shot 37% from jumpers. So 3 HORRIBLE weeks dropped his FG% for the season by 2%... that tells you how bad his funk was.
*** How I got the numbers, going of % of jumpers taken(82games.com), I figured out the # of jumpers he took from his total attempts, then I went game by game in that 3 week stretch counting which shots were jumpers and which weren't.
Tyrus OVERALL FGA - FGM in that 3 week stretch...
2-17
0-5
3-7
0-1
6-12
3-10
1-8
2-5
0-3
3-6
2-9
He shot 27% over that 3 week span, can't remember how bad his jumper was total for that time period, I believe it was 19% or 20%.
So if we were to erase those 3 weeks to see what he did for the rest of the season...
Jumper - 37%
Overall FG% - 48%
So although most go by the season as a whole, most of the season he shot the jumper at a 37% rate and his fg% for most of the season was near 48%. I guess you look at Tyrus as a guy who just happen to have a nearly once in a lifetime horrible shooting night that put him in a huge funk or you expect him to have bad stretches like that every year.
Now 37% still isn't good, but it is an improvement but as Tyrus' confidence grew with his jumper he also put up some very bad jump shots which helped lower his %(some turn arounds, some shots after a pump fake and a man still in his face). I do believe as Tyrus defines his game and what he can and can't do his numbers will dramatically go up compared to where they are now. He's got to throttle down his percentage of jumpers to inside shots though... meaning take a less contested jumpers.
By the way... the way he shot most of the season with his jumpers... 37%(actually a tad under 37% but rounds up) puts him ahead of B.Davis, Iggy, D.Lee, S.Hawes, Westbrook, Big Baby, Rondo, A.Throton, T.Prince, Milsap, T.Young, Deng and K.Love. It also puts him within 5% points of K.Martin, A.Danials and L.James.
