The logic of the move suddenly became readily apparent to Glen Grunwald and a difficult decision was made oh, so easy.

The Raptors general manager was up early yesterday morning, jotting down some of the lists that NBA GMs make this time of year and saw only three big men under contract for next season.

And that's when Chris Bosh became a Toronto Raptor.

Filling a glaring need and drafting a teenager who scouts say has outstanding potential, Grunwald took Bosh with the No.4 selection in the NBA draft last night, eschewing trades and the lure of a 5-foot-11 point guard.

"It was pretty clear we needed to go big, given our roster," Grunwald said after taking the 6-foot-11, 210-pound Georgia Tech freshman. "To get a talented big guy like this in the draft is a difficult thing to do."
