I haven't read this thread except for the last page, but I slightly disagree with your assessment billy.
IMO Hayward has shown he can get to the rim and finish not only in transition but in the halfcourt on side screen-roll - which is really becoming more of the trend in the NBA instead of a traditional 1-4 iso. He's versatile enough that on side screen-roll he can hit the pullup jumper but also go the distance and finish strong with his left hand. No, he's not a 1-on-1 scorer but in the flow of an offense, he's already demonstrated he can score in a variety of ways - including getting to the rim.
Don't forget one of the few bright spots in Game 1 against San Antonio (aside from Favors) was the way Hayward attacked the basket (12-12 from the FT line). Overall Hayward does alot of things well (he mainly needs to gain consistency on his jumper) - so there's no need to pigeon-hole his game as purely a "slasher" (whatever that really means). Scoring-wise he can hit the 3, he can hit the pull-up, and he can get on top of the basket. If he can do that consistently he'll become everything we hope he can be, but if more players on the Jazz focused on attacking the basket and getting to the FT line (*cough* Al Jefferson, *cough* CJ Miles) - the Jazz would've been a much better team.
