“You call yourself a professional, but it’s really taking that to a whole other level this summer,” Caldwell said according to Tim Gayle of the Montgomery Advertiser. “You really have to be a professional now because you have to work out every day (on your own), you’ve got to make you stay on the routine, stay on track, because you never know when that call is going to come.
“The toughest part about this summer is the uncertainty of everything. Usually, you know where you need to be every day. You need to be here at 9 a.m., you need to be there at 3 p.m. Everyone’s on the same track so you know exactly where your football team is.
“Now, some guys are in Houston, some guys are back home, some guys are on vacation. It throws the chemistry of the team off.”
A Montgomery native, the 6-foot-4, 307-pound Caldwell has started 10 of the 23 games he’s appeared in since the Texans chose him in the third round of the 2009 NFL Draft out of Alabama.
