Can Trubisky do it like Dak?

Of the 10 quarterbacks selected in the NFL draft, which concluded Saturday, at least four will be parked behind veteran starters for some time. At least that’s the plan.

The No. 10 overall selection, Patrick Mahomes II from Texas Tech, will back up Alex Smith in Kansas City.

Similarly, third-rounder Davis Webb from Cal will back up Eli Manning on the New York Giants. As will fourth-rounder Joshua Dobbs from the University of Pittsburgh behind Ben Roethlisberger on the Pittsburgh Steelers and sixth-rounder Brad Kaaya from Miami behind Matt Stafford on the Detroit Lions.

But we all saw what happened last year with the Dallas Cowboys. Fourth-round pick Dak Prescott was targeted as a third-stringer, but injuries to starter Tony Romo and ostensible backup Kellen Moore thrust Prescott into the starter’s role to start the season. He shone and won the job. Romo has since retired and gone into broadcasting.

There’s no pressure on the four above rookie backups to do anything in 2017 but learn as fast as they can, providing the vets stay healthy.

The same cannot be said for the other six. If No. 2 overall pick Mitchell Trubisky doesn’t start from the get-go in Chicago or at least overtake free-agent signee Mike Glennon by season’s end, many will view his rookie season as a disappointment.

Ditto for No. 12 overall pick Deshaun Watson in Houston and maybe even second-rounder DeShone Kizer in Cleveland (what, he can’t beat out Cody Kessler?)

As for the other three — thirdrounder C.J. Beathard in San Francisco, fifth-rounder Nathan Peterman in Buffalo and the last pick of the draft, Chad “Mr. Irrelevant” Kelly in Denver — anything other than clipboard duty in Year 1 probably would be a bonus.

In addition to drafted OT Justin Senior of Montreal (Seattle Seahawks, sixth round) and three Canadian free-agent signees (OG Geoff Gray of Winnipeg with Green Bay, TE Tony Auclair of Notre-Dame-des-Pins, Que., with Tampa Bay and DL Eli Ankou of Montreal with Houston), three Canadians scored tryouts at upcoming NFL mini-camps, according to Justin Dunk of Sportsnet.ca. The three are University of Maine LB Christophe Mulumba with Tampa Bay, University of Montreal kicker Felix Menard-Briere with the New York Giants and Simon Fraser University LB Jordan Herdman with Kansas City.

Carolina’s fourth-year WR Kelvin Benjamin showed up a “little heavy” to early spring workouts, Panthers head coach Ron Rivera told the local press. He’s listed at 245 pounds … Teams have until Tuesday afternoon to pick up the fifth-year option on 2014 firstround draft picks. The Buffalo Bills still haven’t indicated whether they will do so with oft-injured receiver Sammy Watkins, the No. 4 overall pick three years ago … ESPN reported that the Indianapolis Colts fired numerous college scouts, including that department’s director T.J. McCreight.
