So I thought it could be interesting to look at Tinsley's stats during that 28 game stretch where he had to step his game. Here are the basic stats:

Tinsley also had an A:TO ratio of 2.8:1. In those 28 games, he made 0 turnovers in 7 of them (25%). The Utah Jazz won 6 of those 7 games. 6 of those 7 games were also at home. That helps sometimes.

Here are Mo Williams stats for the first 21 games of the season:

Mo Williams has an A:TO ratio of 2.5. Up to the game before he was injured, Utah was 11-12. Under Tinsley, Utah went 16-12, where 16 of those games were at home and 12 of them were on the road. Utah had a rough road schedule at the beginning of the year.

Since returning to health and playing time, Mo Williams as averaged these basic stats:

I'm not going to bother looking at Watson's right now. Tinsley's stats on the surface level may look better than Mo Williams, either before, after, or on average of both, but a lot of those games in which Tinsley started were at home. Nonetheless, Tinsley still took better care of the ball and has a far better assist-to-turnover ration when he was starting.

It's hard to know who has helped the team and in what ways this year. Mo made big shots in some games; Tinsley made big steals in other games.

Before Mo Williams injured his thumb, Burks' basic stats looked like these:

After Mo Williams injured his thumb, Burks' basic stats looked like these:

It's encouraging to look at the change in Burks' stats. He went from averaging less than 10 minutes per game, when got to get in one, to averaging over 20 minutes per game in almost every single game after Mo Williams injured his thumb. Notice Burks' 3P% has been 39% (up from 18%) since his playing time went up. This should be encouraging as far as having wings that can shoot (with Burks and Hayward both shooting at nearly 40%). I think Foye's 3P shooting has been in a slump since the trade deadline. He definitely hasn't been shooting 40%. As a matter of fact, here are Foye's stats since the trade deadline:

Foye's been shooting 31% from 3P territory since the trade deadline. He's also been hitting on only 28% from FG range, averages less than 6 points per game, and hardly ever gets to the free-throw line, not that he did before.
