Rapoport added that the Texans want to "be prepared" for unforeseen scenarios on draft week, like Jackson being available for them at the 68th pick, Houston's first selection in this year's draft.
In light of Watson's dynamite, albeit abbreviated rookie season, the Texans are not expected to take a starting-caliber quarterback in the 2018 draft, but by working out the dual-threat Jackson, their staff is its their due diligence on one of the draft's top prospects.
"You understand that there's still gonna be some work to it," Ryan explained. "But you get enough of a feel for, yeah, we're going to be able to get this done. This guy's going to be able to do this."
In NFL.com's mock drafts, Bucky Brooks has Jackson going 29th to Houston's rival, the AFC South champion Jacksonville Jaguars; Charles Davis sends the Louisville star to the Los Angeles Chargers at No. 17; and Chad Reuter has Jackson landing with the Arizona Cardinals at No. 15. Reuter does not see the Texans taking a quarterback with their four third- and fourth-round picks.
Louisville's pro day isn't for another week (March 29). Until then, the Texans, a team already set at the quarterback position for the foreseeable future, will have a head start on the other 31 clubs on evaluating the elusive signal-caller.
