If he averages the numbers in his 2010-2011 season or can replace the TMJ production, I would be very happy.
Just for comparison's sake, so people know what we're talking about here:
TMJ (SR, 2012-12): 36 G, 30.3 MPG,.413 FG%, .393 3PT%, .851 FT%, 9.2 PPG, 3.4 RPG, 1.6 APG, 0.8 SPG
Adams (JR, 2011-12): 19 G, 16.8 MPG, .397 FG%, .340 3PT%, .550 FT%, 4.5 PPG, 2.1 RPG, .9 APG, 0.6 SPG
Adams (SO, 2010-11): 36 G, 28.2 MPG, .388 FG%, .307 3PT%, .680 FT%, 7.3 PPG, 3.7 RPG, 1.8 APG, 1.0 SPG
I don't see any reason why, assuming better health and continued improvement in percentages, efficiencies, etc., he shouldn't be able to replace or even improve TMJ's production.
Also, just for fun, here is Julian Gamble's production (which needs replacing) next to what Kirk did the last couple of years. They play different styles, but we were all thrilled with what we got from Julian (maybe more so because we loved him and his story), but his production is reasonable to replace as well.
Gamble (SR, 2012-13): 36 G, 20.1 MPG, .576 FG%, N/A 3PT%, .481 FT%, 6.5 PPG, 4.9 RPG, 1.8 BPG
Kirk (JR, 2012-13): 31 G, 25.5 MPG, .491 FG%, .387 3PT%, .706 FT%, 6.2 PPG, 3.9 RPG, 1.6 BPG
I'll also note that Kirk's 3PT and FT% were actually better than Kadji's last year.
So, I don't think EITHER of these guys has a huge bar to clear to be useful players, as long as they work hard on both ends and grow.
