I'm not sure that Lamb and Hamilton have the same type of games. Lamb was a better shooter by a decent margin, but Hamilton has a better feel for the game, is a better passer/rebounder, and has a tighter handle. If DHam can get his shot near where Lamb was in his sophomore year, this will almost certainly be his last year on campus.
I think chemistry is the big factor with this team. While we are an upper-class laden team, many of the key pieces have just been added this year. There will be an adjustment period where the players feel out their roles within the team and learn their new teammates' tendencies. While the talent is undeniable, we may have our growing pains early in the year. However, I trust KO will have us playing our best ball come March.
This is not the thread for this, but you mentioned roles which is something i've been thinking about recently. here is what i envision at first blush.
Gibbs 30mpg-Run the O/hit your 3's/defend.
Purvis 29 mpg-Defensive bulldog/run at every chance/2nd option behind Hamilton
Hamilton 32 mpg-O runs through him/Quick, aggressive decisions/natural progression should be perfect.
Miller-27 mpg Glue guy/defend/rebound/do the little things/get 8-9 pts on dirty plays.
Brimah 30 mpg-D.D.D/PnR finisher-shouldnt need iso attempts, but 1-2 per half would be great
Adams 25 mpg-6th man/scoring punch/strong D/2nd ballhandler
Facey 12 mpg-No idea-rebound/defend, if he can get the J to 12-14 feet, him and AB can play without clogging the O
Calhoun 7mpg -doesnt have to do a lot/spread the floor
Nolan 8 mpg-Just come in, be smart, defend and rebound-same thing we've always asked in the same role-more mature player
