Always fun to think about sleepers. On the players mentioned,
1) Stephenson: He would be an insurance/handcuff pick in case of injury to Granger. He averaged 29 mpg last season, and he would need to get into the 30's to possibly break in the top 100.
2) Cole: I don't see getting enough minutes and even then, it would have to take major injuries to Wade and Chalmers. Chalmers is still ahead of him and Lebron, Wade, and Bosh are too much talent to get Cole enough usage. He should only be considered in deep (250+ player) leagues even if that.
3) Henson: I like Henson a lot as a player but the big question is whether he gets enough minutes. New Coach Drew reportedly likes him, but Milwaukee's front court is still full with Ilyasova and Sanders starting. Henson shares backup minutes with Pachulia, Udoh, and some foreign guy maybe. If he can get 20-25 mpg on a regular basis, then he's got utility/bench value.
4) Splitter: I think he can certainly be #2 center on a fantasy team. If he can be drafted in late rounds, he's a sleeper. Depends on the league.
5) Bledsoe: I don't think he qualifies as a sleeper unless you are looking at public leagues. He's got a lot of hype and it's clear that Hornacek will give him plenty of minutes in a high-paced offence. He could get top 40 value, but he likely gets drafted by the middle rounds.
6) Lawson: Yes, not a sleeper, and should be much better than last year. He'll be drafted 2nd-3rd rounds and likely produce his draft value.
7) Valanciunas: He's getting hype, probably not a sleeper. Will be drafted in the middle rounds.
8) Butler: I think he's well regarded in fantasy circles. Good upside. I can see him cracking top 100 value, but likely to get drafted around there too.
9) Olynyk: I agree he's a good sleeper candidate on paper, in particular, because he could get a lot of playing time. Someone like Vucevic comes to mind when you have a big man get a lot of minutes, but Olynyk doesn't really have a low post build or game. The Celtics could play Humphries some minutes at center or, if you want a deep sleeper, Faverani might be a candidate.
10) Gordon: I agree with him being potentially good value if you can pick him up in the late-mid rounds, though I cap his high value in the to 50-70 range, because he'll have Holiday and Evans contending for the ball.
And to toss out a couple of other names:
11) J.J. Redick: He looks to be a regular full-time starter for the first time in his seven year career. Getting 30+ minutes/game. He should be a good pick up in the late rounds.
12) Evan Fournier: He played well when he started late last season. He's young, and could be the starter. Or he could be losing minutes to the likes of Randy Foye and Nate Robinson, and not be much.
Yes, Warriors sold at last!
