Well Russ should be hitting 5th but I don't make those decisions. I have no problem with Colabello in the middle of the lineup as long as his balls keep falling. When the luck runs out he should be on the bench.
Norris never dominated AA and he has only pitched well in AAA over short stints. Good chance he's a reliever long term if he can't fix his control issues. Hoffman at the very least is a backend starter.
If guys are on base bloop singles will score runs. Russ is the better hitter but as long as the balls are falling (he's hitting over .300 over the last couple weeks) ride the Collabello train.
You move Norris because he is good not great and has immense value. This way you limit the risk of Hoffman finding his secondaries as he regains his form. Keep Matt Boyd as a backend lefty and bring him up soon so he can learn from Buehrle (as every lefty in the org should)
If the Jays were getting a true ace like Felix, Hamels, etc then I'd take the 2nd package. I don't want to see a rental come in unless it's a mid-rotation starter (like Niese) that will come fairly cheap.
IMO something like Matt Boyd and a B prospect like DSJr
For a real frontend pitcher I'd be offering up Hutch + Castro + DSJr + Navarro and hope it was enough
Travis has a month of MLB experience. I'm happy with the way he has performed and feel as if he will have a decent MLB career but a month long sample shouldn't markedly change your opinion of him.
