I may not be the most skilled at football tactics, but ....
When I played Madden, I would hear him say that on 3rd down [2nd down in the CFL] you have to throw at least as far as the first down marker.
The number of times the Riders will throw a 7 yard pass on 3rd and 10 is annoying. Throw it the extra 3, get the catch and move the chains. The defense will always let you catch the 7 yarder if they know you can't get any more.
The frantic ends of games show what they can do when they have to throw longer passes.
Is this coaching, QB problems, problems with the receivers, or all of the above?
