Andrew Luck sounds more hopeful even than Frank Reich does about his return. The Colts quarterback said he has started throwing, though he remains in the phase of building strength. “I’m in the middle of sort of a little bit of throwing, strengthening and preparing my shoulder for the throw load of being an NFL quarterback,” Luck said in a pre-recorded interview with Sports Illustrated’s Peter King, via Zak Keefer of the Indianapolis Star. Luck missed all of last season but sounds encouraged by his rehab.
