I like the kid but we can find much better reserve options... I take JO and Wilcox over Semih any and every day of the week.
But I'd take Wilcox at $3M and Semih at $750K as the 2nd string front line, with Steimsma in the Greg Kite role before I'd keep Bass for $4.5 next year.
But I'd keep all of them plus Bass at $4.5M next year as a nice roster supporting Rondo, Howard, and Pierce. Add Jeff Green to the mix...and perhaps one of the current rookies, Brandley, and the two picks prove rotation worthy next season...
I guess for cheap money, these guys are all great players to have around.
